4L60E/65E Stealth shift kit. Cost is 130.00 including shipping. This kit is desigined to increase the torque capacity of the transmission and give firm yet not harsh shifts. This is often the kit of choice for those concerned about warrenty issue's. This is how the this kit's name came about. The kit is designed around having the transmission torn down and yet not noticing that a shift kit has even been installed.

4L60E/65E/70E Towing shift kit. Cost is 215.00 shipped. This kit is designed for all around use in a well rounded truck. It will also work well in cars. Towing in overdrive is much easier done with this kit and without fear of killing the 3-4 clutch set or the 2-4 band. It will shift firm and quick, but not harsh.


700R4/4L60 Race/Street kit. This kit is packaged with all parts neccessary to not only improve the sloppy shifts of the ancient trans, but increase it's torque capacity by almost double in some cases. Even with old and genaric type clutch materials this kit has been known to allow the clutch's/band to grab hard enough to break the older weaker designed hard parts. I wouldn't own a 700R4/4L60 with any real power going through it without using these parts.

The "Fix It Kit". Cost is 100.00 shipped. I have come up with a set of parts that is very good at getting rid of the common 1870 code that is a common problem in the 97'-00' 4L60E's. There is no guarentee that it will fix the problem, but i have about a 90% success rate at the kit fixing the problem which makes it an inexpensive attempt at fixing a problem which is often fixed by replacing the entire valve body for a much higher price.

Many single parts available such as: Boost valves, Servo's, Acumulator pistons, 3-4 W.O.T. shift sleave, 2-Way line pressure mod, Governer Recalibration kits, Recalibrated Governers, Hard parts, Gaskets, Seals, Bushings, etc, etc, etc. If it goes in or around a trans, I can get it.
