4.11 swap shifting, different problem
 

my car likes to redline the living **** out of second, it wont shift out of second unless i let off of the gas down to less than 2/3 of the way depressed, if i floor it it will down shift even when its past the redline and jerk the car to a lower speed it only does this with second, any ideas?

What is involved with this ---- 4.11 swap ----- with valve body shift kit :confused:

Have you checked for codes? Check the TPS. Go a little easier on your car. :p

i forget who makes it, i think small car, it just firms, and speed up the shifts, it required machineing the valve body and replacine a few springs and ball bearings, my local trusted shop reccomended it
the tps is set dead on at 5.2 volts
and i keep forgetting to check tcs codes, i'll do it tommorow

OK. You have checked the TPS set position, but your fault is more likely to result from erratic contact at the upper end of travel. Have a look in my locker for more advice.

Was the fault noticed a short time after the transmission work? Have you asked your trusted shop about the problem?

Yep, Jeff,
I'd ask the guys at the shop that installed the shift kit, as it could be related to it, before I'd try anything else....asking them should be free, since it's concerning work they did.

they said it shouldn't affect shift points,

i'm pretty sure that its not the tps i checked it severial times before i put it in and it tested like brand new, within specs, and went up and down nice and evenly
edit: i bought the car with a blown transmission, it had been sitting for a year or more in a field, it had first and reverse when i started working on it, and i found a 4.11 trannie cheap

OK. You are doing all the right things, but as so often, these do not help.:eek:

Send a pm to svxfiles about his transmission resistor modification for 4.11's...Im dont know if that has anything to do with your problem, or if it could remedy it...But he is the guy to ask:)

cool thanks i just pmed him

The resistor is not involved. Refer my locker where there are details regarding the function of the resistor and the relationsip to solenoid "A" and line pressure.

The kit is most likely intended to raise line pressure at certain points in the hydraulic circuit, in order to increase clutch pressures, as a means of improving issues involving friction.

to add a little more info, the car does stutter a little going from 2nd to third, i've noticed, how bad is this?

Engine stutter, transmission slip, torque reaction, delay in shifting? :confused:
