Our 5,pound, hp 4x4 has chewed through no less than four 4L60E four-speed automatic transmissions in less than a decade. The failures have included: a smoked torque converter clutch, which contaminated the oil and rewarded us with a fried transmission; two broken rear output shafts; and overheated transmission clutches after the installation of more aggressive tires.

We were ready for an upgrade. High-performance electronic overdrive automatic transmissions have become increasingly commonplace, and good rebuildable cores for the venerable yet antiquated GM TH and TH three-speeds are drying up.

Also, we wanted to maintain highway streetability with this truck, so a swap to a three-speed, heavy-duty TH was out of the question.

It is essentially a four-speed TH In fact, the rear half of the 4L80E is nearly identical to the TH, and many internal components are interchangeable between the two transmissions. The only downfall of this swap is that the 4L80E is an electronic transmission that generally requires an additional computer and wiring harness to operate properly. However, the 4L80E can be easily converted to a manually shifted valvebody, which eliminates the need for the computer and much of the electronics and wiring.

This conversion turns the 4L80E into a great heavy-duty analog overdrive transmission that can be easily swapped into almost any high-horsepower 4x4. With our minds shifted into heavy-duty overdrive, we made a call to Monster Transmission to get our hands on a complete 4L80E Monster in a Box rebuild and shift kit.

We also sourced Monster Transmission for a M input shaft, a steel forward hub, and an engine-matched lockup torque converter with a 2,, stall speed.

The company is run by Cliff Whynaught and his son, Mark, who are second- and third-generation transmission rebuilders. The Whynaughts reaffirmed our transmission selection by telling us that the 4L80E is an incredibly durable transmission that you can beat on off-road all day long. The only real disadvantage is the weight, which clearly is not a concern for our 4x4. Here is how our transmission came together. Close Ad. Buyer's Guide. The Future.
