the driveshaft is too short, and the torque arm was disconnected. I didn't put in the 'Vette Servo and huge Boost Valves because I didn't need to and my tranny will last longer because of this choice. I don't chirp the tires as I didn't want or need to. I have short, firmer than stock shifts, all at the right time (I custom calibrated the VB to better match the engine) and it accelerates from a stop nicely. I also selected a 2600 stall converter as I have an anemic V-6 that NEEDS to get up into the RPM band for proper acceleration. I did upgrade to 4L60E internals though and the TransGo High Rev Ring Kit and Release Spring Kit. I only used the V-8 Servo and Boost Valves along with the TransGo 700 Jr. I have mentioned Shift Kits as recommendations when I think that is what is better suited to someones needs as not everybody needs tire chirping shifts, etc.įor example, I just overhauled the tranny in my '88 Camaro last weekend. What Pro Built and I are refering to is the same thing 95% of the time. Now TransGo has been calling them a High Performance Shift Kit so as to better identify with people who don't know the difference. That came about ten years later and was called a Reprogramming Kit. When they came out with the Shift Kit it wasn't actually meant to be a racing kit. TransGo has realized that people often mistakenly call any VB kit a Shift Kit, which is their name. This kit (the commercial version) has a video to aid in the installation too.

The 700 kit also includes some pieces for when the unit is O/H'ed to give it higher RPM capability (at higher RPM, residual oil can drag the 3-4 clutches on even when they should be off). It has the basic fixes that the Shift Kit has and it has features to give the tranny HD/HP capabilities such as greater manual control and higher horsepower and torque handling ability. It is called a Reprogramming Kit or also a High Performance Shift Kit. They do however have something that I think most of you are after though. This kit however isn't available to the general public because of the technical knowledge required. The TransGo Shift Kit corrects this and other problems that these have. This problem is there whether it is a grocery getter or 5.7 IROC. If you don't fix this, it doesn't matter if you put the Vette servo in or the. There are many kit's out there designed to give you firm shifts but if that isn't the cause of your problem it isn't fixing them.įor example, in a 700 you have problems with delayed pressure rise which allows the clutches or band to slip until the pressure catches up. In most cases when someone complains of soft or slipping shifts it isn't BECAUSE if these complaints that they fail but rather there is a malfunction that leads TO the burned/glazed frictions and the poor shift quality is the result. The purpose of a Shift Kit is to correct the weak points of a given transmission. Actually Shift Kit is a trademarked name coined and owned by TransGo Since 1959. Most people associate the term Shift Kit with tire chirping shifts. High mileage vehicles sometimes come in with codes P0841, P0871, P0988, P1775 and P1776 due to wear at the solenoid switch valve bore in the valve body.First off, what a Shift Kit ISN'T. Self-expanding Tuff™ underdrive seal and expander wire.(4) High temperature accumulator seals and expanders (for aluminum pistons only).Non-Shrinking low/reverse piston housing gasket.The kit also includes accumulator spacers to make the releasing clutch exhaust faster resulting in shifts that are shorter and cleaner. Also included is the special underdrive clutch piston Tuff™Seal that fits all models and a new pressure regulator spring that updates the earlier design valve bodies 1989-1991 to the match the revised pressure specifications from 1992 to 2006.

The kit includes a low/reverse piston housing no-shrink gasket as well as TransGo engineered accumulator piston seals and expander wires for the models equipped with aluminum accumulator pistons. TransGo engineered a special gasket for this application made from a non-shrinking material. The delayed engagement forward or reverse and the 2-1 coast downshift clunk is an age associated complaint that sets in when the low-reverse piston housing gasket shrinks and begins to leak. The TransGo SHIFT KIT® Valve Body Repair Kit provides a specially designed tuff seal and expander wire to address this complaint.

The 4-3 coast clunk is the result of a malfunctioning underdrive clutch inner piston seal. Common complaints with this transmission are delayed forward or reverse, 4-3 coast downshift clunk as well as a 2-1 coast downshift clunk. For models with VLP solenoid and sensor, you need # SK 42RLE-VLP. This TransGo 604 SHIFT KIT® Valve Body Repair Kit fits 1989 and newer Chrysler, Plymouth, Dodge, Eagle, Ram, Jeep and Mitsubishi vehicles equipped with the A604/41TE, A606/42LE and 42RLE automatic transmission without variable line pressure solenoid and sensor.
