 Jim Grant's Tech Tips '91 Toyota Camry DX, Slow Take Off
Q: I have a ‘91 Toyota Camry DX with an automatic transaxle with overdrive. I drained two locations of the transaxle prior to removing it to repair a rear main seal in the engine. When I installed the transaxle, I filled one location assuming that the fluid would fill the other end. I road tested the vehicle for 50 miles before the transaxle locked-up. I replaced the transaxle with a used one and since then, it always takes-off very slow. I've changed the filter and fluid and continued to have the same effects. Prior to repairing the rear main seal, the car was running just fine. A: You should know that you’re not the first, and will most likely not be the last, to learn that lesson the hard way. It sounds as if you have an adjustment issue. On the throttle body there should be at least two cables. One is the throttle cable and the other cable goes to the transmission. This cable is the transmission’s means of knowing how far you’re pushing on the throttle. Some call it a throttle pressure cable, others may call it a passing gear cable. In any case, if it is adjusted incorrectly it will allow the transmission to up-shift into a higher gear before the transmission really should. When this occurs the low speed performance is affected. You could compare it to shifting to a higher gear too soon in a vehicle that had a standard transmission. If you’re not sure how to perform this adjustment, take your vehicle to a repair facility that is familiar with performing transmission adjustments. It shouldn’t take them long to get your Toyota performing like its old self again.
