my transmission is automatic i have an 88 2.8l and when driving if i accelerate too fast the transmission kicks down into 1st gear, it also wont shift until about 3500rpms and i'm wondering if i should rebuild it or if it could be something else

Sorry, I'm just not sure. Is the TV cable able to move with out hanging up?

Ok had to look it up. The governor may be bad, also the modulator could be out. I couldn't remember how the trans was set up. You still there? You could check the vac line to the modulator.

Sounds like a bad Modulator to me bro. GL.

look into vehicle speed sensor too... i dont know how it would react when be on a beretta, but on my taurass it had similar consequences

what tranny is that? a 3t40? I think it could be poor sealing on the governor. pull the hose off the vacuum modulator and check it for trans fluid, but i'm leaning towards a governor. they aren't too bad to replace, it's on the right side transmission output, on top. there will be the vehicle speed sensor coming out of the top.

Too bad there's no modulator on the 3-speed auto. The TV cable is the only adjustment.

ding ding!

I would start with making sure the tv cable is adjusted correctly. It does over time stretch and could causing incorrect shifting.

LoL,corrected again on a tranny problem. That's why I don't claim to be a tranny expert. Good call guys!

I'm wrong also! It's an 88. At least I got the TV cable right(ha,ha).
