Does your auto tranny do this?

Star.View · 09-19-2005, 08:58 PM

The transmission was serviced only 3000 miles ago (right before I bought it). The fluid is clean, almost clear with a red tint. Level is correct.

I actually lucked into a nice transmission shop here in town right after I bought it. It wouldn't shift into passing gear (can you say putt-putt?!). The mechanic really liked the supras, and after driving it, didn't believe it was the transmission. He correctly identified the problem to be the throttle position sensor, and then also identified the strange noise in the rear to be the limited slip in need of a fluid change. And he told me I would need a new carrier bearing sometime soon. He said the tran fluid looked good too. At the time he serviced the car, I had not had any problems getting past 3rd gear. It was a couple of weeks later that the first incident happened. Then it was another 500 miles before the second incident! It acts like the O/D button has been hit, so next time I may try to turn it off and back on again.

The mechanic at the transmission place said a rebuild will run around $1800 (he was estimating on the high side).

Does the car seem like it's engine braking in some gears (a manual transmission term) the car seems to stay attached to the gear when the gas is released. My car has and had a lot of these problems. Come to find out that the clutch discs are slipping and the transmission needs a rebuild. Rather than pumping out the $2k or so to get the non-turbo automatic tranny rebuilt, I have put my Supra into storage and am saving up for a 1JZ/5spd swap. I honestly think what caused the problem is that I swap for a Koyo radiator which doesn't have an internal tranny cooler, so had to get an aftermarket cooler. I don't think this did as good a job as the radiator cooler in the stock radiator to dissipate the New Mexico heat that was generated. The result, Fried Tranny!!! Mmmm...tasty.

Car never acts like its engine-braking. I stopped at the tranny shop again, and the mechanic thinks its an electrical problem, possibly a cellinoid. He wants me to bring it by when the problem has become worse, and he can see it in action. That may be a while because since that incident a few weeks ago its been shifting flawlessly. He thinks that if it was the transmission, it would go downhill fast. But if it does come down to rebuilding the transmission, I think I will opt for replacing it with a low-miles tranny. Local guy has a small supra graveyard and has helped me out alot with parts.

What really sucks is the gas mileage. I can't get better than 20. Most miles are city/country.
