The line pressure solenoid defaults to max pressure if not connected. These work well in heavy vehicles and some towing or 4×4 applications. Whether it is Offroad racing, Kings of the Hammer, drag racing or just a custom street rod. All 4L80E transmissions have the old style flywheel. He put a 4L80E behind a carbureted small block in an earlier truck, wired up the tranny to switches and shifts it that way, without a computer. I pulled the pan, inspected bearings, new rear main, and new timing set.
Maybe one of the gurus here with better knowledge of what makes the force motor work can shed some light. You can purchase the full electronic version or if you are on a budget choose our manual valve body no computer needed. This kit does also allow you to convert the valve body back to an electronic auto shift if desired. Rated at 1000 Horse Power. Yep, had all the bolts. Look for some innovative new products in the near future that should make the 4L80E even stronger. What intrigued us was the simplicity of the installation.
Finally we have our stage 3, this is our strongest 4L85E transmission available. I can't imagine ramping up any faster on my L30 and the 5 speed. But I have to get the truck to run first, then I gotta make it shift. One note on the Transgo kit is the aluminum plugs for the separator plate. Truck has new life with that pump, and runs great.
While other shifters can be made to work with a 4L80E transmission, Precision Performance Products is the only company to offer a true correct shifter cable mounting bracket and shift arm specifically for the 4L80E which will help make your installation as simple as possible. Car Craft did a complete comparison of six different transmission controllers for the 4L80E four-speed automatic overdrive transmission in the Mar. Don't know what killed the trans, a low fluid run, running with the manual switches, or the fact that it has over 300K, most likely a combination of all the above. If you need a stronger unit then you may need our stage 2. It seemed too good to be true, so we bolted one in place to test. I don't think that will work as you expect. To update the trans back to electronic control at a later date would require a new valvebody.
This kit comes with Gaskets, Separator Plate, Solenoid plugs and Instructions. The shift pattern is easy to get used to, very similar to a standard H pattern with a manual, but I can flip the switches with my index finger. I Dale Follett can write up how to make it work on a 4L60e too if theirs enough interest into it. We offer several options so you can have one custom built for you particular application. We are also an authorized distributor for Precision Performance Products shifters. Customer responsible for return shipping on core items.
The full manual shifted valve body we offer comes at no additional cost on our stage two and three. Just like the old days. All you have to do is ground the proper solenoid s in the right order and you have a full manual box. This is the one and only fluid release auto shift transbrake for the 4L80E transmission. Includes complete valve body with new internal wiring harness, all new solenoids, and new pressure manifold. Typically this is all you need to put the 4L80E into your musclecar aside from driveline shortening and crossmember mods or fabrication.
We have that covered as well. Perhaps if you don't have an air compressor you could get bye with a dremel, but if you don't have a compressor you maybe shouldn't be doing this type of modifications anyway. We offer numerous services to assist you in getting the best performance from you vehicle. Overheat of the fluid is the likely result. I removed the cup holder on the front edge of the console and mounted the switches there.
There's simply way too many parameters and factors that go into operating those transmissions. Please refer to the core return instructions included with the part or contact customer service for more details. Custom machining is required on the output shaft for proper installation of this kit. The Cool thing about the 4L60E and 4L80E electronic transmissions is that the shift solenoids are not pulse width modulated. This conversion requires permanent modifications to mount a vacuum modulator valve to the valvebody. Customer responsible for return shipping on core items.

Gotta see how expensive this trans build is going to be. Fixed the line, put fluid in and all was well. Fluid was burnt, and there were some small metal shavings in there. All of which I already have. It has two shift modes, and can be shifted manually, via paddles or buttons. .
