Anyone had luck with 4l60e and 2-step?
Stock case on mine. I don't think anyone offers an aftermarket case. My output shaft is billet in the RPM trans. Never before tho and turned a bunch of mid 1.3x's 60 with best being 1.32. I did change the tailshaft housing to a truck since I had one laying around and wasn't using the trans for mounting the torque arm which I think is a bad idea

1.5x 60's here with full weight T/A and self rebuilt 4l60e.
Let loose this past fall after I started spinning it to 7000.
It did not like that lol but also was not set up for high rpms. Lasted 2 race seasons and I drive it like a manual lol.

Yea back to the topic, I used the lnc2000 it worked very well. Now I have Holley efi which controls 4l60e shifting and has built in 2 step

So can’t go wrong with either one then. As long as one doesn’t have a better setup, although all I need it to do is be able to retard timing and build me some boosts!
Dont listen to this guy we all know he's got some voodoo doll 4l80e with pins sticking out mumbling incantations over some chicken bones to make his 60e live.
The first thing people do is throw heads and cam on their car that means they need to rev to 6500 or 7000 to run a number....when rpm is the enemy of the 4l60e, and then they wonder why it broke or call it a POS cause it wasn't designed for 7000rpms.

Little bit of a thread revival but I've had several 1.5X and a **** ton of low 1.6X on a stock 4L60e. Cam only and it sees 6800 RPM every day. 3280# raceweight without driver, 3500 with driver. Stock suspension except for LCA relocations and it pulls the the heavy *** 17x8s off the ground to the 60' marker lol

There are three bolt holes left open on the 4l60e tailshaft housing after the brackets are removed that hold the stock transmission mounted torque arm in place. Once the TA and brackets are removed to be replaced with a tunnel mount TA, this leaves the bolt holes open and mty on the tailshaft housing.
I put the bolts back in.
What IMO should be done instead is to make two triangular plates, one for each side (left and right), and then bolt the plates to the tailshaft housing. IMO that would strengthen the rear most end of the longer tailshaft on the 4l60e. It won't add any weight and won't hurt anything. It's on my to-do list.
