4L60E Trans Go Install Questions

Don't really poke around on the older style GM forums, mostly mess around with Duramax's and Allisons. But had a few quick questions.

I have a '94 K1500 5.0L GMC Sierra. 4x4 with a 4L60E. Just did the basic Trans Go kit as the truck worked fine, just was going to install it as a preventative measure.

 

Ran into the issue of no reverse because I didn't get the boost valve clip far enough up in the bore to the correct grove, fixed that and took it for the first test drive.

 

The one thing I noticed was that the 1-2 shift was very soft and delayed.... 2-3 was nice, smooth and quick like I was expecting and then the 3-4 almost feels non existent. Almost as if its just slipping. I have Engine breaking in all the gears with the manual shift and you can hear an rpm change if you go to 4th under very light throttle. TCC locks in 1st 2nd &3rd. But 4th is so soft you cant really tell.

Didn't have any signs of these problems this morning before the install as the truck ran like a top. Im assuming it has to do with 2-4 band apply.

 

What would be a good place to start looking? or any suggestions? Just trying to get some Ideas before I tear back into it again in the morning.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      4 low is really nice on steep boat ramps.

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
