I have a 1995 Nissan Quest. I'm getting some transmission herky and
jerky when the van is warmed up. I suspect it's the transmission fluid
filter. I plan on dropping the transmission pan and replacing the
filter this weekend.

The Haynes manual lays out a pretty straight forward process to do
this.

I'm asking here if there any gotchas NOT in the manual that I should
look out for? Will any "extra" stuff come out I should lookout for?
:>) When I "inherited" this car from my son (140k miles), who was
given the van, he said the original owner had kept up all the scheduled
maintenance. Together, we have put about 50k miles on the van since we
aquired it.

Any tips, suggestions, comments would be appreciated. I don't want to
screw this up. I think I can get another 50k miles out of the van. I
like it a lot.

TIA,

If your tranny is acting up, it is probably already too late to fix
with a filter change. Changing the filter can be very complicated
anyhow. Carmakers usually design their tranny so that servicing the
filter is not easy. In your situation I would just change the tranny
fluid and nurse the tranny along for as long as it will last. Also,
avoid places to to flush your tranny completely. Old trannies and a
power flush usually = disaster.

It doesn't really have a "filter" just a screen to keep the big chunks
out. You can change it, but it's probably not going to make a
difference. At 191K, it's probably due for a rebuild.

codi/JimV,

Thanks for the responses. The tranny does have a lot of miles. I have
the kit in hand so I think I'll give it a shot. If it doesn't work,
I'll baby the tranny for as long as I can, as you suggest.

Thanks for the suggestions.

Chances are your tranny is about to go, and at this point, it is very
unlikely you can do anything to make it better. If the problem (jerking)
seems to surround shifting, perhaps, but if it's random, you're most likely
ready for a rebuild.

Willy,

I changed the tranny oil and replafced the oil filter. The problem is
about the same, except it seems the problem is far less if I take the
tranny out of Overdrive (press button on end of RH selector arm).

I'm now wondering if there's an O/D sensor that's going bad. I saw all
sorts of wires and assemblies under the engine after I took the
transmission pan off to clean it and get at the filter. Any thoughts
on an O/D sensor going? I really would like to get a few more good
miles out of the Quest. It's a good vehicle for what I need.

TIA for any tips or suggestions.

is less load on the tranny. With OD on, the car gets it's best gas
mileage and the tranny is experiencing the highest load from the engine.
Sine the Quest feels the same in OD after the tranny oil change, I'm
afraid its only a matter of time . . . . . . .

Best thing to do since you would like to keep your minivan is to look
for a used wrecked Quest tranny. The Trany should be pretty much same
from the 1995-2001. I would double check to make sure. You may be able
to find a wrecked, young 2001 Quest tranny to tranfer to yours.

Honestly I'm not sure if the o/d engages as a result of a sensor, but my
guess is that your tranny is going to die very soon. My guess is that the
reason it is shifting better is because, without o/d, the tranny is
experiencing less "tension" (for the lack of a better word) plus, by turning
o/d off, you're sort of forcing it to stay in 3rd (or fourth depending on
the model).

There is no "OD sensor". There's a solenoid that engages OD. OD is when
the transmission is under the most load, so it makes sense that a
failing one will act-up more then.

CD/Willy/JimV,

Thanks for the feedback and suggestions. I'll start looking for a
replacement transmission.

How hard is it to rebuild a Quest tranny? Any good manuals out there
on the subject?
