V6 and 4 spds tranny (110k mile):
1- Sometimes, when i engage R or D position from
park, the tranny does not engage. Just have to put
the shift lever to N position and put it back on R
or D and it will work like a new.
2-Oil smells burns and the color is dark
The tranny was serviced two weeks ago, and except
those probs, the tranny works great on any gear,
no shaking on shifting, no noise, no vibration.
I suspect a seal leak. Should i repair just the seals? Is it difficult to replace? Shold i do replace the tranny by a rebuilt one?

I've recently noticed that the auto trans. shifts quite hard from 1 - 2 (the jerk is quite noticeable). On other higher gears this is not the case.
Another thing is that while climbing uphill from low speeds (starting at say 5 mph), when I get past 40 mph looks like tries to shift to 4 but can't and I can feel the vehicle hesitate.
What can be the cause of the above 2 problems.
thanks

For all those shuddering problems that seem to be trans related, change plugs, wires and coil packs. I've done it and it works. Thanks for your help.
fan belt and water pump went out separately so engine motor mounts were removed and shops raised engine or lowered body each time to gain access to replace them. The last was the water pump and on the same day left town on a trip. Within only a few miles a noise began from the engine area sounding like a hollow wind rush with tappet noise
when I accelerated.
Checking while stopped, there is a noise from the transmission side of the engine (3.8 ltr 6 cyl) that sounds like a very bad tappet rattle from the lower part of the transmission and now a few drops of what looks like trans fluid beneath the trans side of the engine. I am on a 100 mi , 1 week trip and the noise continues to be audible.
The trans has been erratic on rough clunking when changing gears and then sometimes vy smooth. The erratic shifting had been noticeable for approx a year or the last 20,000 miles.
and remove the axle, and final drive (?). All in excellent condition. After reassembly, extensive road tests do show vy rough shifting and continued
noise. Conclusion: transmission bad. Rebuild of trans to include "kit" to correct some kind of a flaw in the 97 GM trans. Firm price to correct all problems and provide smooth normal shifting = $1450 less the $100 if repair is done in the same shop. Along with the vy long list of other repairs on this Park Avenue in it's 64,000 mile history, I understand why Buick no longer uses the slogan "When Better Automobiles Are Built, Buick Will Build Them."
so may as well do the rebuild.
Can anyone comment about this? Tks.
The 100K GM trans.has Dexron 111, i know i own one an the manual reads service with Dexron 111.They just make a good trans. for the money.
Trans drain plugs were eliminated by GM in 1970, as a potential leakage point. Since the pan has to be removed anyway to replace the filter, a drain plug is a moot point.
A properly applied bead of RTV sealer provides a more positive seal than a gasket, which may be overtightened leading to gasket cracking and oil pan flange deformation.
My two Toyotas and Subaru have conventional gaskets and plugs, and have never leaked a drop of fluid.
I still maintain that a 100,000 mile fluid-change interval is fantasy - though considering the lifespan of the rest of the average GM-built car, may not matter much.

Thanks, John
I just got done reading how bad Fram oil filters are and the like, but was curious how bad their tranny filters are. I only ask this because that was all the local autoparts store sold when I serviced my tranny last month. So how bad are the tranny filters from Fram??? If they are bad, what are the recommended brands for tranny filters?
I have a 1997 Chevy K1500, 5.7l, auto, 4x4, extended cab pickumup.
Thanks
Bob
thank you laray

By the way this is not the first person to study different oil filters and find that Frams are less than quality items, this is the only link I had on my work computer.
All I want to know is whether their tranny filters are good or bad or what is the prefered tranny filter brand that people use...maybe you should spend a little more time on the web and check out the oil filters topic (#811) before you judge my "agenda".
Bob
PS: I prefer PureOne or Amsoil motor oil filters
John
joe3891- No worries.... sorry for misreading your post on the agenda thing...good point on the filter study, but it definitely opened my eyes up a bit :-).
Bob
On a similar note I had problem with my 2000 Chevy Tracker which would not go In/Out of 4WDR while moving. It was not a mechanical problem ...the transfer case fluid was recalled. When the fluid was replaced the problem went away.

$1800.00 plus to repair at a GMC Dealer. Im glad I purchased Warranty Gold Extended Warranty. They covered it all, except my $50 ded.
I cured the problem this way - turned battery off for couple of hours (kind of reset for computer and also means clearing some wrongly set variables. After that trans was working like a new. Just want to know what can cause before mentioned problem (wrong variables in computer memory)? It is not too handy to reset computer every week. Car is under warranty but I have no time for visiting shop too.
My problem is that I have a 97 Suburban with option code KNP (Auxillary Transmission Oil Cooler) and this option is not on my truck, meaning I paid for it and it is also posted on inside glove box with all other option codes. But there is no Trany oil cooler installed.
WHATS UP WITH THAT?
engine and auto transmission, and have 167,500 miles on it.
Question is: I have found the gear indicator on
a dash does not match with actual gear, "L" range
in particular. I think transmission works fine,
and the other gears (P,R,D,N,S) match perfectly
with the indicator. Is this a bad sign?
Thank you in advance.
Now Geo Prizm tend to be fairly bullet-proof cars and the car only had 35,000 miles on it. My Aunt is not an agressive driver. Besides, there's not much you can do to the AT to damage it. You're not doing anything most of the time.
What could have cause the problem? Factory defect?

After realizing it I tried last time to switch on everything that can comsume electric current in the car while battery was off to discharge this misteriuos capacitor. And it worked! So no problems since then. Don't have any idea what it might be, don't even know how this clutch works.
Any thoughts???
Thanks
