Hey Guys
1992 CTD auto w/ O.d.
Driving along part throttle , cruising
Feels like the conv. is locking and unlocking in 2nd and 3rd gear
It has a tach and you can watch the rpm's jump up 300-400 rpm when this happens
If your off the gas and slightly decelerating in downshifts too easily
I talked to my local trans. guy and he said he gets this question all the time and said it's sensor/ground related to the engine and not the trans.
something else was prematurly telling the trans. to do it
He said there was a tsb out (my local dodge guy couldn't find it)
that said it was tps, coolant temp. or possiblly something else but he could find his paper and didn't remember what to do
Anybody got a clue?
I did have previous vehicle speed sensor problems and replaced it with a Mopar unit
The problem did seem to arrive shorlty after a trans. flush
(Go ahead and shoot me) I power flushed with a snap-on unit the goes in the trans. cooler lines with ATF dexron II with a mopar friction modifier
I should know better but they insisted the additive makes everything better and the cost of atf was much cheaper
LMK what you think
thanks
