Question about 1990 Buick Riviera
Shortly after install of used transmission, start car, put in reverse - not engage, put in drive - not engage; restart ignition, engages. Sometimes when taking off w/cold engine, tranny slips into neutral. Restart ignition to get in gear....dangerous!! Could this be a computer issue? The car has hardly been used since install & garage says they can't fix it....their only job was to install.
The only other thing i can think of that would cause this problem is the valve body inside the transmission is leaking and/or cracked. I have seen this several times before- it will shift "wierd" and slip also, normally with no pattern whatsoever.
A valve body is not that expensive to change, but I sugest you have it looked at first..

Not a computer issue. Transmission has problems could be filter stopping up, which also means problems.
