Keisler perfect shift 3 install
Hi All,
Im finally getting around to installing the updated perfect shift 3 kit to replace the roll pin design in my TKO 500 from Keisler. Other than removing the tranny, are there any other special instructions for installing this kit? When the roll pin is removed, i assume by knocking it out, does the tranny need to be in gear or N. Are the bolts that hold the kit tourqued or just tightened firm.
Thanks
Ron

put the tranny in "N"
Mine were done with Allens. I have quality 3/8th drive allen head sockets and the gorillas at keisler put locktight or 100 foot pounds of TQ on them and it actually stripped two of the allen heads out. I was pissed at kiesler. Kiesler had a bunch of morons working for them. My kit had numerous problems that a child could see that they were wrong parts or bad.
The block to Z-bar ball stud had bad threads from the factory
The drive line u-joint caps were bigger than the u-joints
The short pivot ball for the clutch arm was so short that It did not disengage the clutch when i first fired up my car. It required pulling the tranny and buying the correct GM longer length pivot ball
The monkey that installed the shifter was a moron. I had to cart the whole tranny down to a shop to drill out and retap the base because of stripped out allen heads

Well, sorry you had problems on your install. The pic you show of the Inland Impire slip yoke shows the cap being wrong.
Once you got up to 35 or 40lbft of torque on the 5/16inch bolt you should have stopped and considered there was something going on before you broke them off. They probably has locktite blue on them. These are not cheap parts, or morons working on them. These are well crafted precision machined parts, with high quality gr5 and gr8 bolts.
The clutch linkage parts are pass thru from Volunteer Corvette, as is the pivot stud. This company is well known for their quality parts, but perhaps the thread was damaged in shipping.
I will let these vendors know your comments, as well as my shipping staff.

The ball stud was a manufacturing blem. I pulled one off of a junk motor
The U-joint cap was for something like a 1350 and the kit was a smaller 1330 with your drive line. I called your guys and e-mailed this picture and they sent out two correct caps.
You guys sent out the improved shifter after my install was complete, I had to pull the tranny a few months later and that is when I had to fight the shifter block allens.
I think that my TKO 600 went in about 2006 and it has performed flawlessly
I was only pissed for a short time 
The kit came with a Sachs clutch and pressure plate. I never used it because I could not find any info about it. I was running a 7500 rpm 427 at the time and I did not want to take any chances. Do you know the Rating of this Sachs clutch?

Loctite blue should break before the bolt. Is there a chance it had loctite red installed accidentally?
Could it have been a case of no threadlocker at all and steel bolt seizing in an aluminum thread?
Any thoughts from the shop as to what the cause of seizing was?
