Re: HELP! 97 TJ Transmission Problem!
 

ok so I changed the fluid and then it drove, but it wasn't perfect, so
i went to the shop and got a transmission flush (100% fluid exchange,
or so they said). Now it drives but its a little hard to accelerate
from a stop and sometimes it wont shift until 3000 RPM. I think my
next step is to bring it in. Suggestions?

Those transmission flushes really don't exchange all the fluid, but most
of the places that do them claim they do. There is always fluid in the
torque convertor that doesn't get replaced, but obviously it is better
than not doing it at all.

Anyway, when you say hard to accelerate, what exactly do you mean? If
you mean that the engine revs up then the transmission engages, then you
probably have clutches that have been damaged, a piston seal with dirt
preventing it from sealing, or a valve stuck in the valve body.

It is very possible that a piece of dirt got stuck in one of the valve
body bores and that there could be a valve sticking. It really doesn't
take much dirt to stick a valve in a bore. This would explain a possible
reason for the high shift point.

If you are 100% SURE the transmission isn't slipping, then I would try
driving it for a while and then doing one more flush. The second option
would be to have a good transmission shop pull the valve body and take
it apart and clean it. The valve body controls the transmission,
including when it shifts, how much pressure is applied to the clutches,
and a lot more. One stuck valve in there can wreak havoc on the whole
transmission.

Well I talked to a trusted guy at a shop and he mentioned the valve
and possiblly one other thing (some electrical sensor I think). He
said that the clutch may be receiving incorrect information from the
gas pedal as to how much pressure it needs to do its job. When I start
from a stop (sometimes) It'll kind've buck back at me and then finally
catch, and I'll (again only sometime) feel a rumble and it'll go,
feels like the clutch is sticking. Anyways he told me that I can bring
it down there and he'll throw it on his machine and drive it a bit to
figure out the problem w/o charging me, so that's my next step
tomorrow morning. Thanks for everyone's help.
