I have just replaced the 4 main sensors in the transmission and that one spring that is known for breaking as well as adjusted the shift bands. Well long story short this was 200 miles ago and i had to redrain the fluid to put a better gasket on. So this fluid is about 150 miles old and is burnt. Anyone know a reason for this? The only thing i can think is that i have the cable that goes to the throttle body and down to the transmission that controls the downshifting disconnected because i cannot get it to return under its own spring pressure. Sorry for the long winded explaination. Thanks for any suggestions
