My 1987 Pontiac 6000 has a front wheel drive, 4 cyl. Engine, automatic trans. 150k. Rebuilt transmission installed a year ago.
The transmission goes into " lock up" at low speed, as low as 30 MPH. Is this adjustable? Also, at times it fails to up shift as it should.
Does it have a throttle position sensor. If so, can it be adjusted?
