Hello!
My LS with 122XXXmiles has now developed transmission problems....About a month ago, I changed all the coils and plugs and the car drove like a dream! Then the very same day after some aggressive driving that I haven't done in years, all of a sudden the trans started to shift very hard from 2-3 (could changing the coils and plugs affected the trans some how???). Now it also shutters between 3-4 and bangs back into 1st from 5th. It shifts fine from park to reverse or drive and vice versa. Ive read as much as I can and some people say its an electronic issue, not a trans issues. Or its a solenoid or a valve body. Full disclaimer, I have never worked on a transmission and know only a little from what i researched online.
I went to one trans shop and they said a rebuild would be $2200 but is a rebuild necessary? Can I have the transmission scanned for codes? There are no codes, at least not yet when I hook up my poor man's OBD scanner.
I can't afford to rebuild, but what is the next step to help diagnose what the real issue is? Or does a rebuild basically cover all the next steps in one? The only thing that has been done, is some Mercon V was added and i disconnected the battery to see if it 'reset's the PCM if it is infact an electronic issue.
Thanks for your help!
