hi, i have a 84 GN and when driving it the other day, after prolly like 30 minutes of driving the tranny starts shifting very weird. It'll shift into 3rd at like 25 mph, and then gets bogged down, or when taking a corner instead of downshifting it'll upshift and bog down till i boost it and then it'll downshift...doing very weird things. This happens in both overdrive and regular drive so i have no idea what the deal is, if anyone has any ideas they are greatly appreciated

Sounds like TCC solenoid is sticking (pretty common problem as the cars age ... usually only happens when fluid temp is higher).

See:
