Ck shift kit install......

[Steve V]

Got my CK kit in today. Fairly simple. The instructions didn't say anything about the pressure regulator assy in the pump. I had Chris's manuel and 3 years in a trans shop exp so it wasn't too hard to figure out. I also removed the cup plug in the valve body for the bleed on the 2-1 coastdown as per the manuels instructions.

Got it together test drove it. 1-2 short and firm,2-3 fimer than stock but softer than 1-2,3-4 just like 1-2. Cool. Drove some more and noticed the trans starting in 2nd gear. Shifted to 1st while stopped and felt a bump as the trans went into 1st. Did several start and stops and exactly the same thing 2nd gear starts shouldn't of removed the cup plug. Then while coasting down the TCC does't let go and car starts bucking geeting ready to stall cause it's in 2nd. Shift to 1st,cars idles normal as TCC is unlocked in 1st. Take off and everthing is the same. Start and stop some more and now it starts going into 1st like it should everytime on the coastdown. All valve were free when I installed the valve body. Pull out into traffic and hit the gas,as soon as it hits 2nd engine falls on it's face as the TCC applys instantly ,pull over unplug it. Still does it. Get pissed off drive home and I nail it,then crusing notice the TCC isn't locked anymore. Now trans acts normal with the exception of no TCC since it's un plugged.

I am a little confused,and thinking I should replace the TCC and see if I can find another cup plug and reinstall it in the valve body.

Anybody? This is a 57k virgin trans/car bone stock. Trans is in excellent shape as is the rest of the car. It's a document 1 owner old woman car,Kirban car at that.

Try takng 1 or 2 clicks out of the TV adjustment. This should lower the line pressure at idle a little but no effect WOT pressures allowing a 2-1. As far as TCC goes, it should be unlocking at coastdown, if not the solenoid may be shot. Do the TCC symptoms seem worse when the trans is up to temp?

2nd Gear Starts Are Usually Caused By Excessive Tv Pressure,sticking Tv Valve Or 1/2 Shift Valve Train.ive Been Leaving The Plug Out For Years And Never Had A Problem.also The Lock Up Solenoid Is Not Exhausting Causing Immediate Lockup After Shift Of Valve In Pump Stuck.

Okay,Chris is it common to have to remove TV after installing your kit?
I am 100% sure there were no stuck valves in it. And yes the tcc is worse when warm. After it warmed up is when the 2-1 started workinh again. The TV adjustment is as it left the factory 20 years ago,that's why I figured it was okay.

I will drive it to work tommorrow and play with it.

Trans is working well today. took 2 clicks out of tv this AM.

Is there anyway to firm up the 2-3 shft,like the 1-2 and 3-4.It's kind of slushy around town,firms up with throttle.

 

[chris718]

glazed friction materials are probably causing poor shift quality.if it gets firmer with applied throttle the pressure system is functioning properly.the kit is not a cure all for glazed friction materials,

It's not too bad I am just a really picky person. I will have the motor and trans out in the spring and I probably freshen the trans while I am there. I am not going to put any seriuos power down with this car so it should live a while. Thanks for your input.:wink:

the thing that gets my attention here is the need to adjust tv cable.this is due to the extra pressure sent to the tv plunger from the new pr spring and not due to the boost valves as they are basically inoperative in drive at idle with 0 tv.the pump pressure is raised enough to cause 90 psi instead of 80 psi(with stock spring)to be fed to and pass thru the tv limit valve(if it was higherthan 90 the tv limit valve would knock it down thru exhausting to limit it to 90 psi ) and arrive at the plunger to be rerugulated as tv boost oil to act on the boost valves in the pump from 0 to 90.the stock gn plunger spring is very short and requires almost 10 degrees of throttle angle in some cases to push on the inner tv valve.this is due to the reduced arc travel from start to finish with the design of the throttle plate and attaching screw for the cable.
