I replaced the sleve that keeps it from doing it, What could I have done wrong? The replacment was from art carr. Also does any one know what top speed would be with 4.11 gears and a 700R4?

 

What do you mean??? Is it just not downshifting or are you free spinning the motor or what???

As far as the top speed goes with a 4.11 and a 700R4...

There are a lot of factors that go into it. Going by the calculator's on this board though it should be somewhere around 137mph. That is assuming you have standard tires, and that you can get to the ZZ4's readline (5850) in your final gear. It will be real hard to get to 5850rpm though in a .7:1 gear, especially wiht TPI when you are moving that fast. Having said all that, you could probaly do 125-130 with a 4.11, 700R4 and ZZ4.

No it just wont shift from 3rd to 4th when I have it redlined in 3rd. I have to lift off the gas.

 

My redline is around 5000 rpm with my stock TPI on there.

 

Did you align the sleeve properly? If I remember right, the sleeve could be turned 180 degrees and still "fit" into the valvebody.

Also, did you reset your TV cable adjustment?
