Ok, I'm reeeeally hoping I can get some good feedback on a problem I'm having w/ my 92 4runner. The problem is that it shifts extremely hard between gears, as if there was nothing to smooth the transition between gears. It's an automatic. It's not that it shifts at a high RPM, causing the shift to be hard. It shifts hard no matter what RPM it shifts at. It used to only do this about 10% of the time. Now it's doing this about 90% of the time. If it's not shifting hard, I cannot figure out how to make it shift hard. It has nothing to do with the EFT Power button, the OD button, or temperature of the engine or the air. It seemed pretty random when it did this only 10% of the time.
I've changed the transmission fluid and filter screen - no improvement. I'm thinking it could be the torque converter, but I don't know much about those.
I also notice that when it's cold, it tends to wait until a high RPM before shifting into second gear. This has gotten progressively worse as the shifting hard has gotten worse...maybe related?
Any advice would be appreciated. I just hate to dump money into it until I have a good idea of where the problem likely is.
Thanks, V
