Thread Tools. Received 8 Likes on 8 Posts. I am in need of your assistance. I have checked nearly everything and find some inconsistencies in my trans plug wiring. I have compared my wiring layout to that of a known working 4L60E in our plow truck. I welcome any and all input. What trans was this arrangement set up to control? How about the shift solenoid? The note in parenthesies indicates the position in the PCM plug. Attached Thumbnails.

Hooking up VSS buffer. The trans now works mint!! Cooling fan.

If you own a car with an electronically operated automatic transmission, chances are you have the 4L60e transmission. They deliver performance swiftly and are loved by many car owners though it has flaws. So in this article, we will be talking about the evolution of the transmission, its price, and the cars using it. We will also discuss some common problems with the 4L60e transmission and how to fix them. The 4L60e transmission is an electronically operated 4-speed transmission designed for vehicles with longitudinal engines. It utilizes four forward gears and one reverse gear and has a vehicle weight rating of lbs. Before adding the recommended 4L60e transmission fluid, this transmission weighs lbs. However, with the transmission fluid, it goes all up to lbs. Depending on the size of the Torque converter used, the transmission can house a total fluid capacity of either 8.

Designed for longitudinal engine configurations, the series includes 4 forward gears and 1 reverse gear. The 4L60E is the electronically commanded evolution of the Turbo-Hydramatic R4 , originally produced in The two transmissions cannot be differentiated from the outside. The 4L65E shares the same exterior parts but have stronger internals such as 5 pinion planets compared to 4 in the 4L60E. They also have different input shafts and torque converters. This happened in for trucks, vans, and SUVs, and for rear wheel drive passenger cars. In , a bolt-on bell housing was phased in along with a six-bolt tailhousing for S Trucks and S Blazers and beginning in for all other applications. Beginning in a new mm torque converter with improved higher-capacity internals, mm style input shaft, and mm style pump was also introduced on models coupled to a Gen III Small Block. It weighs pounds without transmission fluid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, 4 distinct gear ratios can be achieved.

The first shift sequence was very strange. Top trans line to top radiator line. Thread Tools Show Printable Version. It doesn't matter what position it is in. Find More Posts by Nowhereman.

Edit: I went back and looked at the original post, he is giving the truck away to charity in a month Thank's again.

The vent tube is just to vent the transmission of air. How about the shift solenoid? The first shift sequence was very strange. Twin Turbo lq4 breaking up tipping into boost.
