Just bought the car..its a 94 Z28 with the obvious 4l60e..its been rebuilt with a shift kit and billit trans pan..stock stall...on the interstate the car turns almost 2400 RPMS at 70mph..and will not lock up..do these care have a lockup solinoid?

whats everyone elses RPMS at say, 70 MPH? mine are just over 3000 at 80!!!

any help or advice would be appreciated..thanks

 

ok i see now that it does have a lockup solenoid...any idea how much these runs, are they common replacements and how hard to install? is this thing internal or external?

 

What is your rear ratio? and on lockup first I would see if its being commanded on and is there and SES light. What stall is the converter?

 

Im assuming its the stock stall....a cant flash it past about 1200 RPMS so id say its stock...the gear ration im honestly not sure of? i bought the car in its current state. Its appearing they arent 3.23/3.24.

any ideas how to see if it is commanding lockup? and there is no SES light.

and on another note...60 MPH is dead on to 2000 RPM.

 

Sounds like you have 373 to 410 gears based on that

 

yeah i was fearing that...guess ill mark the DS and the wheel and atleast try to ball park ratio
