Project Mustang #79: Alignment and transmission issues

[@J-B-po8ht]

Some info I ran across- Intermediate Band Not Releasing: A problem with the intermediate band not releasing can cause the transmission to shift down to 2nd gear. Vacuum Modulator Malfunction: A faulty vacuum modulator can also contribute to this problem, as it affects the transmission’s ability to regulate gear shifts. It's suggested to check the vacuum modulator before tearing into the transmission. Valve Body Assembly Errors: Incorrect assembly or damage to the valve body can also cause shifting issues, including dropping down to 2nd gear while cruising.

Did you happen to check your kick down adjustment and make sure that it's not sticking? I think they're supposed to be a spring on the kickdown to hold it up

[@ProjectBarn]

I took the kickdown completely off, so it shouldn't be interfering with anything

Just thought have you thought about upgrading to a either an AOD or converting to manual?

[@ProjectBarn]

Maybe in the future I'd go an AOD, but not any time soon

I’m not the best on transmissions, but have you tried putting a T in the vacuum hose and running the line to a gauge you cn read while your driving? Maybe to low vacuum pressure might cause this. What do you think?

[@ProjectBarn]

I did put a gauge on it. Has good vacuum, so I know that's not it
