Shift points
« on: December 22, 2007, 09:48:57 pm »
At full throttle my truck shifts 3500-3800 rpm is this normal.I reved the motor in park and it can hit 6000rpm at about 6200-6300 I think the valves started to float.

Sounds ok to me. Any higher then that it feels the motors gonna tear outta the hood. Are you wanting a higher shift point?

I would suggest getting a shift kit installed then. They're only about 50 bucks but it's about 150 to have it installed in the vehicle. You can alter the shift points and it also make them more solid. Be careful on free-reving the motor, It's a good way to float a valve and smoke it. It's not just how high your motor will rev, it's how high it will rev safely.

If it's breaking the tires loose shifting to second, then I don't know what more you could want  ;D
If it's already got a shift kit then IDK

when I had my stock 400 small block in my truck when I first got it it had a shift kit that had just recently been installed along with a tranny rebuild. at full throttle it would rev to about five grand and chirp the tires every shift. 3800 sounds really low.

If your tranny doesn't wanna shift out of 3rd above 40 I would check to see if your kickdown cable is installed properly.

What transmission do you have? If you have an early shift (not including the TH400) adjust the TV cable tighter. If you have a TH400 replace the modulator with an adjustable one and check your detent solenoid.

You went the wrong way with your cable. Depress the tab and push the pluger towards the firewall. Then depress the throttle WOT (engine off) and that's your base adjustment.

I don't understand what you said.AT full throttle I can still pull the cable out 1/2 inch,is that to much.
