Alright, it's the '92 Camaro.. with around 202K on it, original everything.

Yesterday I was trying to get by some SUV so I could take my exit, floored it.. but no downshift. After the exit, a little later I tried it again, just to see if I did something wrong the first time (Though I don't know how I could've...) and it did the downshift and did like it usually does.

Today, my mom comes in complaining the RPMs were around ~2800 - 2900 at 55mph (Pretty high). I'm taking it out later to see if I can get the same problem.


Is the transmission going out?

Have you checked the trans fluid?

When was the last time you had the filter changed? Or the fluid?

Also on the older automatics, there's a vacuum line that runs to a small cylinder (called modulator). Check that the line is in
tact and there is no fluid in it. If there is fluid, replace the modulator.

Do you know which transmission you have?

If you love something, set it free. If it comes back, it's meant to be.

If not, point & laugh when it flies into a woodchipper.

It's a TH350 or TH400, we took it for a drive (After tightening some vacuum lines^^) and did some pulls on the highway, and a little normal driving. It did fine, I guess that was it.

Good.

I think the TH 350/400 also have a band adjustment. If you have a mechanic you can trust, you might want to get the trans serviced.

If you do it yourself -

READ THE MANUAL FIRST!!! Screw up on the band adjustment & you burn up the trans, QUICKLY!

From some of your other posts, I get the impression you haven't done a lot of work to cars.

Not exactly. Dad changed shift points (Chipped? Not sure.) as it kept breaking trans clamps. Haha. I don't think the fact of the Corvette servo helped, hah.

If you have overdrive, it's probably a 700R4 or similar (that shoulda clicked when you said it was a '92). Not completely sure on that, I'm a Ford guy.

Not as strong as the TH 350/400, but they can be built if someone knows what they are doing.

Indeed. I'm more of a Honda guy myself. :P

202k out any auto transmission would be respectable. I wouldn't be too trusting of an automatic transmission with that many miles.

And if the fluid has never been changed, it might be a bad idea to change it. I've read a lot whrere people change their transmission fluid at like 150k miles and it stops working in like 2 weeks.

It looked fine, it was still nice and red-ish colored.

Righty - The crud in the fluid was probably the only thing keeping it together! :P

Most manufacturers recommend changing the fluid once a year, but who does?

Sky - Did it smell burnt?

I change mine every 25k, or about 2 years. With my next paycheck, I'm hoping to change mine. And a lot of time, deposits and stuff are keeping the transmission together. The detergents in the new fluid will eat up the deposits that are keeping it going.

Yeah, old trick is to put trans fluid (Type F) in your motor oil a week before you change it. The detergent cleans out the carbon
deposits in your lifters. In older engines you also get a 50/50 chance of starting to smoke a little.

Unless it was recent, it would probably be a good idea. Haven't worked on many VWs but a Haynes manual should tell you
what you want to know about your golf. They're less than $20 US at most parts stores. I'm guessing you can get the gear oil
(or ATF in some cases, check for sure) will cost about the same.

If you haven't found this yet, you might be interested.
