Transmission O-ring dipstick Size?

[lomax07]

Whats the OEM transmission o-ring dipstick size?
whats the best size to use to prevent leaking?
I brought a kit with sizes 5mm - 14mm id x 19mmod x2.5mmW

It's a standard, not metric size. Also the same size as the oil dip stick o-ring. 5/8 I beleive...just take one with you to any parts store and match it up

Ok thanks. Can I possibly use the o-ring on the top of the trans dipstick or the one at the top off the engine oil dipstick.

No, that o-ring is a different diameter

Ok cool i'll wait til tomorrow to get the right size that one screw on the dipstick is a real pita. I hate I have to take it back off.......... Mine is leaking around the dipstick I was tryna use some permatex to stop it but is was a Fail.
Thanks alot and Merry Christmas

There are tons of screws on these cars where gear-wrenches are a near must, this is one of them. With a 10mm angle or flex head, you can get it easy from the bottom, with gear on the head, handle pointing towards trans, no problem

hell yea i found out awhile ago i brought a set from Pep Boys for $29.99 sizes 8mm-19mm.
I used a 10mm for that screw but it was still a pita and even more of a pain when i realized after i changed the o-ring. I used the wrong size and it was still leaking

I was never able to find the exact size O ring in a standard or metric kit. If the diameter is close, they are not thick enough.

Then I just got them from the dealer, they call them a seal, they are cheap and worth it, no more leaks.
