whenever i hit the throttle to pass someome up or to go up a hill, my automatic 86 berlinetta downshifts like normal, but then it'll just rev and it wont go any faster. also if i give it than normal throttle, it stays in a gear way tooo long.. any ideas? torque converter? tranny slipping? all fluids are full also..

 

It won't shift into OD at WOT.

 

you didnt even answer my question. i know it wont go in OD when its wide open throttle.. it wont go any faster when i get on it, regaurdless of what gear i am in..

 

How high of rpms are we talking here. The stock engine in 3rd gens top out at 4000-4500 rpm. You just don't have the power to go faster.

 

What exacly does it do? Downshift and not shift up even though the rpms have come up to or past the redline on the tach? If it shifts into second alot of 700-R4s wont shift back up to third at WOT. I think its due to a dirty TV valve.

 

ME Leigh knows what he's talkin about. Frankly, I find that my 86 Berlinetta reaches the max of it's powerband in speed at around 70. After that it feels like my mom's 4 banger Buick Skylark lol.

But you should still be able to gain speed and such, just not as fast as within the power band. You may want to check to see if the plug wires are toast or what. That could cause it... or plug wires. I doubt it's a air problem since you're doing this on the freeway/highway.

Try doing some general maintenance. Spark plugs, spark plug wires, cap, rotor, oil (synthetic is always a good choice), oil filter, fuel filter, and if you dont know when your O2 was changed last, I'd suggest changing that while you're at it as well. All together w/ the O2's it will probably run you about 100 dollars on things that you should replace anyways. After that if the problem persists, you are atleast on the right track with a good running base to show where your true problem really lies.

 

i just changed all of that when i got my car smogged about two weeks ago.. i dont have this problem just on the freeway. .also on the street it wont go any faster when i get on the gas, but if i gently roll on it itll gain MPH but only if it is flat or slightly downhill..

 

i will check out that TV valve.. if i gently, and i mean gently, roll on the throttle it will go into every gear, even though it stays in each one a long time.. once i get on it and it downshifts ( from any gear) it revs and doesnt gain MPH

 

What is the speed and at what rpm does it occur?

 

any speed and rpm.. someone suggested that the TV cable may need adjustment..

I said in your other post that now your description sounds like the TV cable needs adjustment.

 

awsome thanks

 

The method they posted there never worked for me. Do a search on the transmisson/drivetrain board. Transfixleo(?) posted the method for adjsutment that works the best.
