Hello everybody,
ive just recently signed up for this site but i have been here plenty of times before to look up various problems and solutions for my 95 accord. now to the problem, this girl i know just recently got her a 98 accord and turns out the tranny is slipping when it goes to shift in 2nd and 3rd. well i did a little research on this issue and found out apparently this generation has lots of tranny problems (prob doesnt help the previous owners filled the tranny to the top with fluid >_>), but anyways what i figured we could do to save her some money is to get a different year model(prob a 93-97) to put in it since all the others of that gen are just gonna go out. i was wondering how much of a pain that would be if it is possible, and if it would even be worth it to get one of those or just buy a new or rebuilt one. shes got a automatic f23a1 4 cylinder motor with 263xxx miles on it. thanks in advance for reading and feedback, also my apologies if this is in the wrong section. (like i said BRAND new posting)

 

Unlike the 90-93/94-97 Accords and related Bullnose Preludes/1st gen Ody the '98-up cars use fully electronically controlled/monitored transmissions.
They are pretty similar looking to the older units but the newer units lack the throttle valve cable, and have added pressure sensors that communicate with the PCM.
Without the input sensors going to the PCM, it may never command a proper shift.

The only other option would be to change out the PCM/harness to an earlier 96/97 unit and she can keep OBDII but use the earlier trans if emissions are an issue. Or go to OBDI altogether and use the ECU/TCU combo. I have no idea if it would be possible to use a '98 MT PCM and '95 TCU, somehow make the two work together, and then install a '94-97 trans.
But you would still need at least the earlier cars AT TB shaft with the second cable attachment point, if this is even compatible with a newer TB, or replacing the TB if the TPS and sizing is the same.

Fairly sure by now most shops now of the PRV issue with the '98-'02 transmissions. The weak part is the problem is a simple fix, but due to the case design it requires near complete disassemble of the trans to get to the valve body.

 

Just drain it and refill it to the min mark first and see what happens. And it's the V6's that have the bad auto trannies. Just do that and see what happens first.

It may be better to just pull the tranny and have someone rebuild it if it is indeed bad.

synchrotech is a pretty respectable online tranny store

Well I see Mike has responded and appears to be giving a better detailed post. As he said the obd2 ecu's have the tranny portion incorporated. It wouldn't be easy to use an obd1 tranny.
