TRANS-X

[GMNewProductInfoCenter]

MY TRUCK HAS QUITE A FEW MILES ON IT (192,00) SO I THOUGHT I'D GIVE THIS STUFF A TRY.  I LIKE IT! IT ACTUALLY FEELS LIKE IM GETTING A LITTLE MORE LOW END TORQUE FROM THE TRANSMISSION... MY TRUCK WILL "CHIRP" THE TIRES  ON HARD ACCELERATION WHEN SHIFTING FROM 2ND TO 3RD.

Is this a transmission fluid or additive? If so, how does it differ from B&M trick shift? My tranny shifts hard, but only occasionally chirps, I suspect it is the weight of the SUV on the rear tires as opposed to a pickup, combined with the wide tire and tread I'm using. 1-2 shifts feel like someone rearended me, but rarely a chirp.

It's very harsh, in fact I'm taking the 1-2 accumulator spacers out tomorrow (from the B&M transpack) and putting one spacer and a spring back in to soften it a little. (down to "heavy duty" mode from "competition mode"

I did notice the trick shift tightened it up quite a bit due to its lighter viscosity, but went back to dextron to try and tone it down a bit.

it is an additive. and i have a little more under the hood than a 350.

FWIW, this product has been around at least 30 years. I've used it a lot in many different applications. Unlike most tranny additives, this one will not swell up the seals 'til they get so soft. they start to leak. I have also used this every time I installed a tranny kit regardless whether there had been a problem or not.

It will hel deglaze everything in the tranny which means better, more positive shifts. I don't know about the B&M product but this one in not marketed as a shift improver.

Hope that helps.
