There is a regualator valve inside of the valve body in the tranmission. Unfortunately, the transmission in this car must come out to get the valve body out. The way I understand it is, when the transmission and the fluid get good and hot, the fluid becomes thinner and there are rubber seals...
Trans fluid level is fine. I changed the fluid and filter about 18,000 miles ago. The old fluid looked fine and the pan was clean. No leaks either. It shifts on time and very smooth. The only exception is when it starts surging after locking-in. This happens until I hit cruising speed. If I...
I have heard that there is a hydraulic pressure test that can be performed to confirm or disprove a faulty regulator valve in the valve body. If it is the regulator valve, the hydraulic pressure should change when the surging takes place. There is a vacuum modulator on the transmission, but I...
Thanks for the input. I did install a transmission cooler; the largest I could fit in, about 11"X11" (3/4" thickness). It helped considerably. The engine temp is quite a bit cooler too.
I'll check into the Redline fluid. Prior to the transmission cooler, it would surge when...
Are there any risks for (besides decreased fuel economy)in the case where voltage is applied directly to the torque converter control solenoid in order to unlock the torque converter lock-up? Will switch unlocking it cause any damage to other components? This would be in the case where the...
