The Texas Speed 4L60E Performance Transmission is a fully rebuilt and upgraded 4L60E for two-wheel-drive LS-powered GM vehicles from 1998 to 2006 that use the 13-pin case connector. Texas Speed rates the unit for up to 600 rear-wheel horsepower, making it a direct replacement for a worn factory transmission in a cammed, bolt-on or mildly boosted LS car or truck.
Inside, the transmission gets all new frictions and steels with a 7-clutch GPZ 3-4 stackup, heavy-duty front and rear sprags, 5-pinion front and rear planetary gearsets, a reinforced input drum with billet overrun apply piston, a wide red 2-4 band on a new reverse input drum and a heavy-duty sunshell. The rebuilt pump uses a .500 boost valve and High-Rev vane rings rated to 9,000 rpm, and the rebuilt valve body carries a heavy-duty shift kit that allows full manual downshifts from 3rd through 1st and holding 1st or 2nd at any speed. A Corvette servo with billet 4th apply piston and cover completes the build. Texas Speed covers the unit with a 30 day warranty from delivery.

FAQ
What vehicles does the Texas Speed 4L60E 2WD performance transmission fit?
Texas Speed lists it for 1998 to 2006 two-wheel-drive GM LS cars, trucks and SUVs that use the 13-pin 4L60E case connector. Verify the connector pin count and drivetrain on the original transmission, since the connector changed over the production run. For 2007 to 2008 vehicles Texas Speed offers the 15-pin 4L65E, and for 2009 to 2013 the 17-pin 4L70E.
How much power is the Texas Speed 4L60E rated for?
Texas Speed rates this rebuilt 4L60E for up to 600 rear-wheel horsepower, supported by the 7-clutch GPZ 3-4 stackup, 5-pinion planetaries, heavy-duty sprags, reinforced input drum and upgraded pump pressure.
What is upgraded inside the 4L60E compared to a stock rebuild?
Beyond a complete overhaul kit, the unit gets a 7-clutch GPZ 3-4 pack, heavy-duty sprags, 5-pinion planetaries, a reinforced input drum with billet overrun piston, a wide red 2-4 band, a heavy-duty sunshell, a .500 boost valve pump with High-Rev vane rings, redesigned 3-4 return springs, a heavy-duty shift kit and a Corvette servo with billet 4th apply piston.
Can I manually hold gears with this transmission?
Yes. The rebuilt valve body with heavy-duty shift kit allows full gear-lever-controlled downshifts from 3rd through 1st and lets 1st or 2nd gear be held at any speed or rpm.
What is the difference between the 2WD and 4WD versions?
The internal upgrades are the same. This listing is the 2WD case for two-wheel-drive vehicles; Texas Speed sells the 4WD case separately for the same 1998 to 2006 model years. Order the one matching the vehicle's drivetrain.
Does the transmission come with a warranty?
Yes. Texas Speed provides a 30 day warranty from the time of delivery. The transmission ships in a plain, reinforced double-wall box.
