auto tranny only shifting manually?

mckeddie · 04-22-2007, 09:52 PM

thinking of getting a 97 TJ (trading my YJ for a moderately built/easier to sell TJ). anyways, the TJ is a 4.0l auto with 84,000. the problem with it is, you have to shift it manually. if you put it in Drive, it takes off REALLY slowly. i'm guessing it is sticking in 2nd or 3rd. anyways, think this is something that a flush would fix or is this more of a rebuild or replace it type of problem.

If this jeep is yellow, I know the past owner. If you can not get it to go in first at all, then chances are not good for a simple flush fix. Probably needs a rebuild. Those trannys are cheap to rebuild. Without first gear in an auto trans. means that the gearing will be pretty steep! :(

no, it's black. look in general, and there is a pic of it, it's from stanton ky.

anyways, it will go in if you shift it manually, just won't do it if you leave it in drive. manually up and down shifting works fine. just if you leave it in drive, it accelerates really slowly (i have no first hand experience with this, as i haven't driven it/seen it in person yet).

Does it have an external shift control box?
I've heard of them going bad on some cars & only letting you shift manually.

Sounds like it has a manual valve body installed. in my tranny, it starts in whatever gear i put it in. If i put it in 3, it starts in third. Ask if the tranny had any work done to it.

If the trans is a stocker, then a manual valve body does not exist from what I researched in the past.

Isnt that the AW-4 Aisin trans? Same as the Toyota A340. There are a few shift solenoids that go bad in the trans.

Here is a Toy FSM that details the solenoids....might help if its set up the same as the AW-4... http://personal.utulsa.edu/~nathan-b...autotrans.html
