4L60E Clutch Module 1987, new and ready to install. Fits the 4L60E. Ships fast from the USA.
The Exedy EFK173 is a full friction clutch module for the GM TH700-R4 and the 4L60E that replaced it, listed for 1987-up units. It is the friction half of an overhaul: new lined plates for every clutch pack, with high energy material in the 3-4 clutch where these transmissions fail most. If you own a late-80s C/K pickup, Blazer, Camaro or Firebird with a 700R4, a 1993-up 4L60E truck or SUV, or a hot rod running either unit, and it slips, flares between gears or smells burnt, this is the set rebuilders reach for.
There was no 4L60E in 1987. GM built the hydraulically controlled 700R4 until it was renamed the 4L60, and the electronically shifted 4L60E arrived for 1993. The two share the same basic clutch layout, which is why one friction set covers both. So a 1987 vehicle takes this kit as a 700R4 rebuild set.
Both transmissions use five multi-disc clutches and a 2-4 band. The input housing carries the forward, overrun and 3-4 clutches, the reverse input clutch has its own drum, and the low/reverse clutch is in the case. Each friction plate is a steel core with bonded lining; under piston pressure it locks against its mating steels to hold a gear member. The EFK173 includes:
It cross-references to the Raybestos RCP96-087 and BorgWarner 34036KIT modules, both standard 700R4/4L60E replacement sets.
Note which gears slip and check fluid condition. If the 3-4 clutch is gone, find out why: low line pressure and leaking 3rd-gear circuits burn this pack repeatedly. Read our 3-4 clutch pack diagnosis guide first, and if the complaint is 1st gear or neutral-to-drive slip, see the forward clutch and sprag wear guide.
Listed for TH700R4, 700R4 and 4L60E from 1987 up. Plate counts and 3-4 stack height vary with year and with previous modifications such as extra-capacity 3-4 kits, so count the frictions in each of your packs before ordering. If you are unsure, send us your year and VIN, or the transmission ID tag, and we will check it. More parts for both units are in the 4L60E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, as a 700R4 set. The 1987 vehicles used the 700R4, and the kit is listed for 1987-up 700R4 and 4L60E units because both use the same five-clutch layout.
No. The EFK173 is friction plates only. Reuse steels only if they are flat and undamaged, or buy a new steel set for your year.
It uses high energy 3-4 frictions, which handle more heat than standard paper lining, so it suits stock rebuilds, towing trucks and mild performance builds. High horsepower builds usually also add a stronger 3-4 backing plate and extra 3-4 capacity.
The kit cross-references to the Raybestos RCP96-087 and BorgWarner 34036KIT friction modules.
On a 4L60E, clearing adaptive values after a rebuild helps the computer relearn shift pressure. A 700R4 has no computer control and needs the TV cable adjusted correctly instead.
