Torque Converter

(Click here to view the original thread with full colors/images)

Posted by: midwestbird

Im looking for a converter for the Thundermark and was wondering what stall and brand people are running here? Ive heard 3200 and up for the stall range and I just thought that was a bit high? Any info would be great.

Posted by: unity

I hear the stock Mach 1 is a great one to get. Its very affordable too. Might be worth checking into. I do not know much beyond that, all I know is I have stock and I WISH I had replaced it when all was out.

Posted by: 98LSC32V

Mach 1 torque converter won't give you any performance over the stock converter, it is stronger though and will let you rev the car higher with no problem.

Posted by: slowmkviii

Get a mach 1 converter and have the stall moved higher this would be much cheeper than a after market one I got my mark converter bumped up for $170

Posted by: Rich88LSC

I have pretty much decided to go with BOC 10" 3500 stall. They are made by Circle D. If you have a place that can cut open the Mach I converter that might work as well but I don't think the Mach I converter has any more clutch material then stock. A lot of aftermarker converters has close to twice the clutch material as the stock Mark converter.

As soon as I have a chence to get under the dash to get the catch code so I can order an Xcal at the same time I'm going to order one.

Thats the same one that I was looking at.

Posted by: Tobin

Just call somewhere and tell them what your looking for, most places will work very well with you. I'll be going through Alan at Dirty Dog when it comes time to do mine. http://www.dirtydogperformance.com/c...ode/cat_3.html
You may also want to consider a J-mod while you are at it. I'll be using this one, since I want to get a new valvebody anyways.

I'm saving up for rear & gears, convertor, and j-mod to do all at once. Then I'll enjoy my whole new animal.

Goodluck

I would say 3200 rpm will be good. I had that in the mustang with a 4v it was nice.

Posted by: driller

3500 rpm stall speed ROCKS!

That's what I had with the 4.10s.

Posted by: kustomizingkid

I would recomend any converter by Circle D, Lonnie sells them. I would also stall somewhere between 3200-3500, that 10" unit is nice.

Posted by: midwestbird

there is no problems driving at say 2500-3000 rpm on the highway with a stall thats around 3200-3500. At about 65-70mph with the 4.10s Im up in the rpm range. Thanks for all the input.

Posted by: Markviiiedrea

Midwest converters is a great place to have them rebuilt. One brand I would say not to get is EDGE they break and they refuse any warenty clams.

It should be locked up at so no slippage cruising on the hwy. No problems.

Posted by: kustomizingkid

I would go with midwest converters for any stock rebuild, but I don't know about performance.

Posted by: Markviiiedrea

They are what's in mine and slowmkviii and two other Mark's that I know of, havent had a problem. But go with what you like.

Posted by: MonsterMark

I have a Edge Racing 3200 stall I'm selling. Anyone PM me if interested.
Doesn't go with the turbos very well for street use.

Well I ordered mine and a tune today. I'll have some feedback in a few weeks

Posted by: midwestbird

Rich88LSC..keep us posted. Really looking forward to what you think of that setup.

Posted by: Rich88LSC

No problem. Trans is being built as we speak. I am going to get the trans/TC in first and give it a week or two to make sure there are no problems before I do the gears so it will be probably at least a month before everything is done and the gears are broken in before I will really see what it can do.

Posted by: MediumD

Don't bother with under 3500 IMO...

Posted by: JMiles_T

I had a 3200 stall converter for a while, but I didn't care for it at all.

Bear in mind that I still have the stock 3.08 gears on my car.

You'll likely have a better experience with your rear end setup.

Posted by: AbrahamLincoln

who sells the 3500 stall converter and how much do they usually cost? As far as the shift kit, why spend 150 bucks when you can just do the j mod your self for free? Essentially isnt that what that BC unit is? They do the Jmod on the valve body and then mail it to you for 275, then you mail them your core and refund you 75?

Posted by: kustomizingkid

I bought a predone valvebody personally, the main reason was that I wanted a professional to dissasemble, clean, modify, and reasemblethe valvebody for me. It was a choice on my part for the security of getting the job done right without haveing to worry.

There are a lot of different converters out there. Price will depend on brand, size, quality, etc. If I was buying a converter I would go with Darrin at BC Automotives 9.5 inch converter with a 3500 rmp stall.

The JMod does not touch the valve body in any way.

Posted by: AbrahamLincoln

tell me why i should spend money for a shift kit, when i can do the j mod for free... if i mess up the jmod - then i can justify buying a shift kit.

Jmod does the same thing as the shift kit correct?

Posted by: AbrahamLincoln

the bc doesnt list prices - anyone know how much they go for, the race one and the pro series one from BC automotive?

Posted by: 98LSC32V

Around $900-950 for the 9.5' BC automotive one which is of the highest quality. They also have a 10' one which is very nice as well and cheaper.

Posted by: kustomizingkid

I know exactly what the jmod does, you simply modify the sperator plate allow more fluid to flow through the valve body, not modifying the valvebody but you do have to dissasemble it.

I simply chose to have a profesional mess with the valve body for me, it was my choice and my money.

My BC Auto valvebody was like $250 total after shipping and everything included.

Darrin has a new supplier for his torque converters that can finally build exactly what he is asking for. I will be buying one of the 9.5" units this summer.

Posted by: slowmkviii

With be controls you do mod the vavle body and this helps with torque correction for a longer lasting tranny also has some up graded parts

Posted by: Rich88LSC

I ordered mine from Lonnie at BOC. 10" 3500 stall.

Posted by: kustomizingkid

That converter is a Circle D product I beleive, I think I'm gonna drop one of them in my vic, and put the 9.5" in the Mark.

Posted by: Rich88LSC

Yeah Lonnie told me the 10" TCs were from Circle D and the 9.5" is from another manufacturer but I cant remember who.

Posted by: kustomizingkid

The 9.5 is from a new guy on the scene, I talked to Darrin about it, he says the new guy is Awesome.

Posted by: AbrahamLincoln

how about some prices

Posted by: Rich88LSC

I don't want to say how much to be fair to different vendors but a good converter ain't cheap. Count on at least $500 or more depending on your needs

Posted by: AbrahamLincoln

fair what do you mean fair its a free market economy we dont live in China! Capitolism baby!

i called bc or whatever they sell their base racer one for 725 plus shipping. seems like a pretty beastly unit.

boc entry level one is 500 bones - anyone rockin this? they also got a bumped up one for an extra hundred. and other steps above that.

ive read of an edge piece? not sure about that one any info would be helpful.

Anyone rockin anything different besides these?

Posted by: Rich88LSC

ok fine. dam

I order the $500 10" one from BOC. I have talked to a few people and think the billet front cover is added weight that I would not benifit from in a mostly stock car i dont plan on revin to 7k+ very often. My car is driven daily so I wanted something that will act close to stock for the m-f commute

Posted by: AbrahamLincoln

thanks Rich! what stall do you have it set at? Can you adjust it with these aftermarket units? Or is those things once you set it, its set in stone and a big pain of you ever wanted to adjust it. say 3200 for daily 4k for track etc.

As for having the Mark unit customized for a higher stall... anyone done this?
And as for the original poster with the thundermark, why not go Tremec! You got the added benefit of a manual option with those birds!

Posted by: Rich88LSC

I ordered a 3500 stall. The stall speed can not be changed without removing the TC from the car and cutting it open and reworking internals. Not something you would want to do yourself or very often for that matter.

As for reworking the stock unit it can be done but after market units are designed for more abuse. Among other things there is a lot more friction material for the lock up clutch, sometimes anti ballooning plates, better bearings etc. For a stock car a reworked stocker may be fine but IMHO it's worth the extra money to get an after market unit.

Posted by: AbrahamLincoln

agreed. thanks for the info. Let me know how you like that unit once you get it installed!

great lolol, no i dont think he wants a manual, its too tough to be consistent at the track, not to mention he has always said he cant shift fast enough

As I posted before in this post I have I think he got it to 2800 for under $170
that is worth it to me with how tight money is for me much cheaper than $700 for the one I want and before you say I could get by with a $500 unit why If I mod later I would need the better one then any way

Posted by: midwestbird

Rich88LSC, did you get your converter yet??

Posted by: Rich88LSC

I'm looking at it now. Actually dropping the car off tomorrow to have the new trans installed along with it. I still have to order gears and a trac lok so I don't know how much fun it will be with the stock 3.07 open rear end.

I should have some feedback by Monday for you. I'm out of town from tomorrow afternoon until Saturday night.

Posted by: newguy

and does anybody know what the stock converter stall is on a 2002 mustang gt,,I heard 2500??? cause I have both mk and stang both out of a 4r70w of course,and I am changing my trans and want to put the converter with the bigger stall of course

Posted by: Rich88LSC

Well I picked the car last night. It got a fresh beefed up trans along with the converter. I did not flash it with the Xcal and I just ordered the gears and trac lok a couple days ago, so the car is totally stock beyond the converter and trans mods.

You can tell when you take your foot off the gas the car does not want to creep like stock. And I am not crazy about how it feels trying to drive normal. You definitely have to give it more gas then stock especially on any incline. I think gears might help this a little and once I get used to it I don't think it will bother me as much. The trans hunts between 2nd and third unless you give it a decent amount of throttle, but I think that will be taken care of with the new tune once I have a chance to flash it. It seems like once it hits third the TC locks up and the rpms drop to much and it downshifts back to 2nd.

The good part though is the car rips compared to before. The open 3.07 rear is killing me though as it will much more easily spin a tire buy just punching it from a stop. I have to take of easier before I put my foot into it. Best part is after about 75 miles the mileage is showing 13.8 and still climbing. I was at 15.7 before so if I can get to over 14 with the new TC and not keeping my foot out of it I will be quite happy. I figure the Xcal will give me a mpg or two back and the gears might actually help since most of my driving is around town. That is if I can start driving normal again with all the newfound fun under the right foot.

Posted by: ONEBADMK8

Baumann Engineering ALL the way for the 4r70w'S AND THE eDGE IS wicked AS HELL INSTALLED MANY AND OWN THEM TOO, NEVER HAD ANYTHING BUT holy $hit WHEN i HIT THE GAS. lISTEN TO THESE VIDS, SOUNDS LIKE THE CAR IS A STICK AND WINGS UP REAL QUICK THEN unloads THE TIRES!!!

Soory about the caps too lazy to retype! LOL!

Posted by: Markviiiedrea

Edge = CRAP! I had to get mine rebult with less the 1000 miles on it, they wouldent warenty it, said "our prouduct cant brake" I will never by from them again and to any one else is thinking about it, save the money and go somewhere else!

Ok I feel better. sounds good, you will love it when you get gears, it will really wake the car up with the right stall

Posted by: midwestbird

Rich88LSC....let us know when you get the gears installed. Im saving up for the 3500 converter as we speak.

Posted by: ONEBADMK8

I personally never had a problem with Edge. I went my best 1/4 mile times with ProTorque.

Posted by: midwestbird

What stall speed would/did you go with? I have the 4.10s if that makes a difference.

Posted by: Rich88LSC

I spend some time talking to peolle before I decided. Went with 3500 factoring in going to 4.10s

Posted by: newguy

can anybody here tell me what converter this is for it only has numbers on the back>26095 and 279 looks like it fits a c-6 or c-4 or a 4r70w same style and bolt patern as those trans

Posted by: midwestbird

I was looking at BOC and saw that the stage 1 doesnt have the anti baloon plate, is this necessary or is it a typo? The stage 2 has it but it also has the billet front cover and its $100.00 more.

Posted by: kustomizingkid

Sounds like some good upgrades for $100, I'd just get the upgraded unit.
