1993 Chevy Lumina Euro 3.1L Auto 4 speed trans.
The tranny was slipping and the car would stall at stoplights. I replaced the fluid, filter, and gasket and the slippage stopped. The car would still stall at stoplights. I noticed a tranny fluid leak so I took the pan back off. The car is on blocks. Do I need to replace the TCC solenoid before I put the pan back on? If so, where is it? Thanks in advance.
