Three 4L60E bench tools in one set: T-0151 low/reverse spring compressor, front pump alignment band, and J-36418-C Teflon seal installer and resizer.
Anyone rebuilding a 4L60E out of a Silverado, Sierra, Tahoe, Suburban, S-10 or Camaro runs into the same three jobs that a socket set cannot do: compressing the low/reverse clutch spring to get its snap ring out, centering the two halves of the front pump while torquing them, and installing Teflon sealing rings on the turbine and stator shafts without cutting them. This kit covers all three. It contains a T-0151 style clutch spring compressor, a stainless pump alignment band with a wing nut, and a six-piece anodized aluminum installer and resizer set in the J-36418-C / ST-1503 style.
The 4L60E low/reverse clutch sits at the back of the case with its return springs held by a cage and snap ring. Without a compressor, there is no safe way to take load off that ring. The front pump is built as two halves, body and cover, bolted together around the converter hub bushing. GM's service information describes the pump as a 13-vane variable-displacement unit, and its rotor and slide only work if those halves are aligned when the bolts are torqued. Off-center halves bind the gears, wear the bushing, and can leak. The shaft sealing rings carry pressurized oil to the clutches; a ring nicked on install leaks oil, lowers apply pressure and is a direct path to a burnt clutch pack.
If you are chasing low line pressure or a burnt 3-4 pack, the cause is usually somewhere upstream, and our 4L60E common problems guide walks through where to look. For pump-specific diagnosis and measurements, read the 4L60E pump rotor and bushing wear guide before you split the pump. Knowing which parts you are replacing tells you which of these tools you will lean on hardest.
The kit is built around the GM 4L60E and also listed for the 700R4, 4L60, 4L65E, 4L70E, TH350 and TH400, and the listing also names the TH250, TH375, 3L80 and 4T80-E. Those less common cases vary, so check each tool against your unit before using it. For 4L60E work it covers the full 1993-2013 truck, SUV and car run. Browse the rest of our 4L60E parts and tools to round out the job.
Pair the kit with a full 4L60E master rebuild kit for seals and frictions, and refill with Dexron VI ATF when the unit is back in.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes on a 4L60E. The pump is two halves bolted together, and torquing them off center can bind the gears, wear the bushing and cause leaks. The band holds the outer edges flush while you torque.
It compresses the low/reverse clutch return spring cage at the rear of the case so you can remove and reinstall its snap ring safely.
Installing the ring over the cone stretches it. The sizing sleeve squeezes it back into its groove so the drum slides on without shaving or cutting the ring.
Yes. The kit is listed for the 700R4, 4L60, 4L65E and 4L70E in addition to the 4L60E. Check each tool against less common cases before use.
A master rebuild kit with seals, gaskets and frictions, any hard parts that measure worn such as the pump rotor or sun shell, and Dexron VI ATF for the refill.
