Four-tool 4L60E bench set: T-0158 drum spring compressor, T-0151 low/reverse compressor, and J-36418-C plus ST-1503 Teflon seal installer/resizers.
This set is for the DIY builder or small shop doing a first 4L60E rebuild out of a Chevy Silverado, GMC Sierra, Tahoe, Blazer, S10 or Camaro. It holds the four special tools the teardown keeps calling for, and you would otherwise end up borrowing them or making them from pipe and C-clamps. You get the T-0158 drum spring compressor, the T-0151 rear clutch (low/reverse) spring compressor, the J-36418-C turbine shaft Teflon seal installer and resizer, and the ST-1503 stator shaft Teflon seal installer and resizer.
Take the unit apart in order and you reach these tools in roughly the order they are listed. After the pump comes off, the input housing and the reverse input drum come out. Each one has a piston under coil springs and a retainer held by a snap ring. Set the drum on the T-0158 base, which takes drums up to 6 inches, and screw it down until the ring is free. On reassembly you reverse the same steps. Near the bottom of the case, the low/reverse piston sits under its own spring in the case itself, with no drum around it, which is why it needs a separate tool. The T-0151 hooks the case and compresses that spring so you can pull the ring and the piston.
The two seal kits come in during the build, not the teardown. The turbine shaft rings go on with the J-36418-C cone, and the stator shaft rings on the pump cover hub go on with the ST-1503. Once each ring is in its groove, slide the matching resizer sleeve over it and leave it there until the mating part is ready to go on.
A harsh or soft shift with a P0748 code, or a slipping torque converter clutch that sets P0741, can be a solenoid or valve body problem, not a reason to pull the case. Work through our 4L60E problems and symptoms guide first. If you have lost 3rd and 4th, check the sun shell splines, which is a common 4L60E failure. If the unit is coming apart, our guide to the bench tools you actually need covers the measuring tools that go with this set.
The listed fitment is the GM 700R4, 4L60, 4L60E, 4L65E and 4L70E. The T-0151 also works on the THM 250, 250C, 350 and 350C. That covers 1993-up 4L60E trucks and cars as well as the earlier 700R4 they grew out of. Two lengths of turbine shaft were used across the family, so hold the seal tool up to your shaft before you start. If you are not sure which unit you have, send us the year and VIN. The full lineup of parts is on our 4L60E parts and tools page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The T-0158 drum compressor comes first, for the input housing and reverse input drum. You reach the T-0151 near the bottom of the case for the low/reverse piston. The seal sizers come in during reassembly.
Yes. The set is listed for the 4L60E along with the 700R4, 4L60, 4L65E and 4L70E. Hold the turbine seal installer up to your shaft before you start, because shaft length varies across the family.
Do not. Fit new rings during a rebuild and size each one with the resizer. A reused or unsized ring is a common cause of low clutch apply pressure after a rebuild.
No. The T-0158 is a screw-type bench compressor, and the T-0151 works inside the case, so you do not need a shop press for these springs.
Buy a master rebuild or overhaul kit for the soft parts. You also need a holding fixture, a dial indicator to check total end play, and an inch-pound torque wrench for the valve body bolts.
