TCC Solenoid

In the valve body of the transmission, This can be check by its PWM (pulse width modulation) The wire connection is a seven pin connector at upper front of trans case. What you are describing does not seem to be a TCC problem. The TCC comes on at above 50 MPH. Drive at above 50 MPH step on the brake pedal not to stop the vehicle, just slightly,.enough to turn off the TCC. See if it make a difference then do it going toward 30MPH.

Modulator possibly went bad

use a Mityvac or any type of vaccum pump vaccum tester tool (avail at ay parts store) and hook it to the vacuum nipple of the vacuum modulator on the side of the trans, pump the tool to see if modualtor holds vacuum, if it doesn't it is defective.

1990 Buick Riviera Transmission won't shift out of low.

On my Vauxhall/Opel Senator I snagged a cable from the auto box which left the car in a 'limp home' mode. I'm no mechanic but once the cable was re-attached the car was fine.

1990 buick lesabre when in drive seems like its in neautral

Hello, I'm not sure if you are still dealing with this problem, but here are a few tips.
1.When the car is running and at normal operating temperature, check the transmission fluid level. If the transmission fluid level is low, this will cause the Transmission to slip when in drive.
2.If you transmission fluid level is low, this usually indicates you have a leak. Transmission fluid does not need to be changed like other fluids such as oil.
3.You may also want to add a "stop slip" agent to you car, this may help or possibly correct the problem.
4.If all else fails, I would recommend you take you car into a certified Transmission shop. Please vote or rate this reply if you found this reply helpful.
