I got this 1991 Corolla DX wagon with 3 speed autotran one year ago and used lightly for weekly grocery etc. The car had 136000 miles and I added 4000. It looks like that the previous owner had regular maintenance and I carried this on. There have been a few problems since I got the car: the biggest was that it stalled in front of traffic lights in wet weather, shortly after running and came totally normal after running for a while, especially on high way. I solved this by change the distributor and roter after some online research.
There are still some problems: 1. when I wait in front of traffic light or idle the car in D gear, there are some vibrations. The vibrations are not constant and they come and go. It gets worse and better sometimes. Especially when I drive locally, where lots of stops and gos, the change-oil light will be on sometimes, shortly after oil changes. The light goes off when the car starts to move. 2. shifting the gears to D normally cause the car jerk forward. If I do it slowly, it's less obvious. But shifting to other gears is fine. I therefore always shift slowly with care. 3. When the car accelerates from <~20 mph to >~20mph, the car jerks: the engine first rotate fast but the car accelerate slowly, then feels like the torque is caught up by the tran, engine to a lower speed and the car accelerates normally. I checked the ATF and it looked pink and smell OK ( though I am not sure what's really OK). I took to a mechanist and he said it's normal for this old 3 speed trans and I'd better let it be.
Please give some suggestion, thanks!
