hey i am working a 1998 plymouth what i think is a voyager or something like a t/c or a caravan... with a 3.8l v6 and a what i think is a 4lte transmission... it's got the solenoid packs on it like it is one... when the owner is coming to a complete stop every once in a while the transmission seems to kick out of drive and go into neutral... i test drove it today and couldnt get it to act up. pulled codes to find if it's a solenoid and something eles no codes relating... only egr flow code... he also said that when he goes to put it from park to drive it sometimes acts up and stays in neutral. he said when it is acting up and the transmission is in neutral he puts it in the 3 selection and it takes off just fine... also i performed a stall test on it and the engine revved up 2000 rpms what is the stall for that vehicle or round abouts, it didnt seem to high. i dont think it's slipping... the trans fluid was just changes along with the filter another possibility, checked it and it's full... i thought maybe it was a engine mount of a misadjusted cable linkage but that all seems good and tight... are there any tsbs and anything that i can check to find out what it could possibly be. if it was an internmintant short or open to one of the solonoids or anything eles to the transmission wouldnt it go into limp home mode and be in 3rd gear... this problem seems unreal but i guess it really is happening could it be inside of the tranny i have been inside of one before and i asked the owner if when he had his fluid changed did anyone say anything about there being anything in the fluid and he said no... idk i would really like to help him out if anyone has an idea i'm fresh out of them thanks

 

Could it be that the fluid was just getting old and ratty and he fixed the problem by changing it? You indicated that the owner recently changed the fluid and filters. Has he experienced the problem since?

 

yes he changed the fluid and when he was on his way to my place to have me check it over about 50 feet after he started it and took off he said he came to a stop for an intersection and he hit the accel. pedel and it felt like it was in neutral so he dropped it back into 3 and it took off like it was normal. on another site a guy said there is a tsb about the low reverse piston seals were changed... i dont know if anyone has seen this problem and fixed it... the other guy from another site also said it would happen mostly when it was cold and that is what the owner said on the way over to my place about 50 feet after he took off from his drive way... the two clutches that are applied in 1st gear are the low reverse and underdrive right? 2nd is 2-4 and underdrive... 3rd is underdrive and overdrive and 4th is overdrive and 2-4 it has been alittle while and i dont have a manual yet on the transmission correct me if i'm wrong...

 

Check your control linkages. It sounds like there may be slop in there.

 

Yes, you're right about the clutches if it's a 41TE. I'm still not convinced it wasn't the fluid. Just draining and refilling doesn't get all the old fluid out, it takes some driving to flush it through. If it's not acting up, you are not going to be able to isolate the problem, so any repairs are just guesses.
