Probably. Sounds like your band is shot (it's applied in 2nd and 4th gear.

First check your governor - make sure the gear isnt stripped.

If the governor is in good shape and gear is fine, drop the pan and see what's at the bottom. Lots of metal or burnt clutch material is found, put the pan back on with a few bolts and yank it for overhaul.

If nothing remarkable is found, air check for band apply via the little exhaust hole on the pan rail surface, just underneath the servo. If the servo applies, the band itself is likely burnt. Yank it for overhaul.

Only you can answer that for yourself. I feel it's easy but that's because Ive done it numerous times.

Everything's relative...

The transmission had about 1 quart too much fluid in it do you think that could cause any problems
