1988 Ford F-150 XLT Transmission Problems
I have a 88 ford f-150 XLT with a 5.0 motor, A few months back my rear end started to act up, I pulled out my Ring and pinion, Spider gears, and carrier, and replaced them. Now that I have everything working my transmission wont shift, It goes into Reverse, Neutral, and Drive, but never shifts out of the lowest gear. Before my rear end went out my transmission worked fine.
The things we have done to trouble shoot the issue.
Checked the transmission fluid and was low 2 quarts, so we filled it back up with transmission fluid.
We checked for a Vacuum Modulator but has none to find, It appears to be all electronic.
We have tried driving it down the road, putting it into neutral and back into drive but nothing changed.
