Default 90 buick that won't shift outta first * for a co-worker *

Gents.

One of the guys I work with, his grandmother has a 90 buick with a 3800 and 54k on it. It sits cause it won't shift out of first. He would like to fix it as gas in his truck is killing him.

I searched an found things like solenoid or TCC problems. Could someone enlighten me as what can be done.

He tells me the fluid is red, as this is his grandmothers car he has no idea how long it was doing this. Is there something He or I can check or test to see if it is not a dead tranny.

Thanks

check the vacuum line going to the vacuum modulator on the front of the tranny, and also check the throttle valve cable going from the throttle body to the transmission and adjust it

I would do whats been suggested, but Id add to check the fluid properly(warmed up engine, running, level surface)

Theres also a possibility of bad fluid/clogged filter.

Give it a shot, my brother had a 96 cavalier that we thought the trans was toast.
We changed the fluid/filter, and cleared a code, all was good.
