4L60E wiring harness differences

WHAT ARE THE DIFFERENCES BETWEEN THE VARIOUS 4L60E/4L65E/4L70E TRANSMISSIONS? Looking for an Affordable, In Stock, Plug and Play wiring harness for your LS Swap? PSI sells Standalone Wiring Harnesses for GM Gen II, III, IV, & V LS/LT based engines and transmissions. These harnesses include the Gen II LT1/LT4, Gen III (24x) LS1/LS6 and. Right, and difference between the 94 and 95 are the trans harness is 1 wire that controls the PWM solenoid in the 95 trans., and how the TCC tables are set up to duty cycle the 95 for the PWM. The pin is pin 6 in connector d, the blue connector on the PCM, to pin U on the trans. This ia a brown wire on 95's None of the '93 -'97 4L60E's are directly interchangeable, except '93 and '94 and '96 and '97!!! Here's a list of yearly differences that will show you why. Yes, some years will fit in others and may not even throw a code, but there will be an issue in the long run. The big issues become forced 3-2 downshifts, and converter lock up issues and burnt lock up clutches The 4L60E has been produced since the early 90's. While retaining the same basic gearing, it has undergone some design changes from time to time. It's important to understand that when selecting a new internal or external wiring harness for it, since the harness didn't stay the same for every year.. Make Sure the Harness Fit Well I think changing the complete harness would be a lot of work!!! But I have been comparing wiring diagrams from my 1994 Service manual and some 1995 wiring diagrams online. They are literally identical including the page number, except for one extra wire used in 1995 trans for the TCC PWM control solinoid

The size & weight The biggest difference is probably the size & the weight between the 4L60E and the 4L80e transmission. The 4L80e is much larger and heavier than the 4L60E. The 4L60E has a weight of 150 lbs without fluid and a length of 23.5″, while the 4L80e has a weight of 236 lbs and a length of 26.4″ ScottiesHobbies.com Presents: Follow along as I install a new wiring harness on my 4L60e transmission out of my 2001 Chevy Tahoe.Click to buy:4L60E harness:. It also uses a different wiring harness. Like the 4L65E it uses 5 pinion front and rear planetaries, has an improved design and hardened reaction hub and sun shell, has a shot peened input and output shaft and an extra clutch in the 3-4 clutch pack. There are other differences as well but this highlights the big ones GM B and D-body 4L60E differences by year: is more work than its worth due to the amount of labor involved in properly routing an additional wire into the powertrain wiring harness. TCC Mod (method 2): Leave the PWM solenoid unplugged but installed. On the valve directly to the right of the PWM solenoi

The electronics of the 4L80E and 4L60E also shows a major difference. In this case, there is a disparity in the transmissions' wiring harness and the transmission control unit.

A 4l60e is a 700r4 - the only difference being that one shifts electrically and the other shifts hydraulically. The 4l60e shifts with electronic shift solenoids. GM figured out it was easier to control the transmission electronically than via the hydraulic circuits. Plus you can change how the trans shifts while driving, which can be a real. I know for a fact the 4l60e was used in '94 (as well as the 4l80e). I know the '94 &'95 PCM will support both the e trannys--not sure if the wiring harness contains all the wires, though. 88XJ, Chevy 5.7L, Edelbrock MPFI, NV4500, Atlas, D44's, high steer, ARB's, 7 custom semi long-arm 3 or 4-link lift, BFG 33x12.5-15's

Wiring Harness, Sensors and Controllers. Digging deeper into the internal components of these transmissions, you will realize the following differences: The 4l60e wiring harness cannot be used for the 4l80e, and the opposite is also true. There is also a difference in the sensors of the 4l80e and those of the 4l60e Pre-1993 4L80E transmissions use a different internal wiring harness and pass-through connector. This early harness has a problem with leaking fluid at the pass-through connector. GM recommends upgrading to the newer connector and wiring harness. Because of this, we do not provide a wiring harness for it. I Note the differences between the HD and Performance versions. The Heavy Duty line is available in both 2 and 4WD. The Performance and Heavy duty 4L80E. This transmission will take the place of a 4L60E transmission with the use of #10X below (LS1 type computer only). • All new wiring harness • New EPC Solenoi In 1995 the 4L60E changed slightly, and an additional solenoid was added to the valve body. This required an extra wire to be added for 1995 models. You can determine 94/95 harnesses by looking for Pin U on the transmission connector. Also, 1994 4L60E transmission WILL NOT work properly with 96-97 PCM's. 1996-1997 were OBD2 PCM's

So, ANY (Truck or SUV) that is a 1500 will get the 4L60, a 2500 chassis will be get the 4L80e. You need to understand this if purchasing an engine from me. 4L60's & 4L80's are not electronically interchangeable. The tune in the ECM is different as well as the main wiring harness Primary wire is typically an 18-gauge wire and is the most common wire found in wiring harnesses. The larger wires that feed heavy-draw circuits are typically 14- to 12-gauge. The wire in Painless Performance kits runs a little larger than the standard; the primary wires are 16-gauge, with 12-gauge for heavy-draw items such as the headlights M30 is the 4L60E. M32 is the 4L65E. M33 is the Hybrid Trans. M70 is the 4L70E. 2000 to Early 2005 4L60E use the 13-Pin Harness with Green Connector. Non ISS Sensor in Pump. Will interchange with eachother.

The 4L80E transmission is the advanced progeny of the legendary TurboHydramatic TH400 automatic transmission, and is based heavily on the 400 in both parts and strength, yet featuring an added overdrive gear, a lock-up torque converter and advanced electronic controls The next 2 or 3 letters identify the model of the transmission.These numbers tell us the application, engine size, wiring type, and solenoids. If you find 2 letters, the transmission is made between 1982-1985.. If you find 3 letters, the transmission is made between 1986-1993.. The last way to identify if it's a 4L60 or a 700r4 is to look at the rear of the transmission for the Aux TV Cable.
