Before adding the recommended 4L60e transmission fluid, this transmission weighs 146 lbs. It utilizes four forward gears and one reverse gear and has a vehicle weight rating of 6000 lbs. The 4L60e transmission is an electronically operated 4-speed transmission designed for vehicles with longitudinal engines.

We will also discuss some common problems with the 4L60e transmission and how to fix them. So in this article, we will be talking about the evolution of the transmission, its price, and the cars using it. They deliver performance swiftly and are loved by many car owners though it has flaws. It’s one of the most versatile transmissions ever manufactured by General Motors and has since evolved. This is true because it’s one of the most common automatic transmissions in the US car market today.

I'll take care of that when I change the filter and install the drain plug (if it doesn't have one) in the trans pan.If you own a car with an electronically operated automatic transmission, chances are you have the 4L60e transmission. He also recommended the HD2 shift kit from the start since it's a heavier car and I'm looking at eventually ~600hp with the right turbo. He says I'll be fine with the Force Motor frequency of the 4T65E. Īnd here, this should answer a lot of questions about the 4l80e, if you havent' already found it. In stock form the 4l80e will handle about 450hp, if you got more than that, you'll need to install a TransGo HD2 shift kit, also better clutches and steels, that will get it to handle about 750hp, over that you need to replace the drum, input shaft and a few other hard parts, then you're good to about 1200hp, though if you need over that, check this guy out.

If anything you'll burn it up, but the main thing I'd be concerned about is it applying the right line pressures, the 4l80e has low line pressures to begin with, one of the first mods they do is raise the pressure. I have the switch now so I tested it off of the transmission so I hit P, N, and 1 (L) and the logic from the 4T65E worked with the switch so I'm going to assume that the rest of it works and run with it.

This diagram shows the pin outs for A, B, C, and P but doesn't show the way the switch works on the inside to show the logic structure of the Range Switch.Ĭonsidering this logic table is not in the Hydramatic manual for the 4T65E, I'm doubting its in the Hydramatic manual for the 4L80E. I've been able to decypher it from the diagram in the Mitchell wiring diagram for the 4T65E and it uses A, B, C, and P (Parity) switches. What I really needed is the same is the Transmission Range switch logic tables. The good news is that GM uses the exact same logic tables between the 4L80E and the 4T65E as far as the A, B, and C on the Pressure Manual Valve switch. These are not the same as the 'Transmission Range Switch' Logic Tables. What Squirrel is posting is what Mitchell wiring diagrams is calling the 'Automatic Transmission (Transaxle) Fluid Pressure Manual Valve Position Switch' Logic Tables. Thought I'd bring this up since someone, someday is going to hit this thread and see the posts and either get the wrong idea or be confused. Stupid wiring pigtail is like $76 new for one and $37 for the other! Here's what I mean, the 4T65E switch logic looks like this:Īlso if anyone has a used range switch and harness pig tail they'd be willing to sell I'd be tickled to get ahold of one, the local U-Pull-It yard doesn't have any and the other yards don't tend to want to sell things like that. The pin labels line up, as do the wire colours, between the 4T65E and 4L80E switches but I wanted to see if anyone had any experience (or the logic tabels for) the 4L80E range switch since I can't find it online, just a pinout, to see if they have the same logic structure between them.

The 4L80E shares this switch with the 4L60E mounted on the gear select lever. Going through the input listings on the transmissions, the 4T65E controller needs to see the gear range switch. I'm messing around with planning how to get my 4T65E controller to run a 4L80E transmission.
