Default 4L60e How Tough ?

I'm gonna be adding some horses to my 5.3, a stall, and shift kit question is if I fry the trans will these parts fit the 4l80e, or can the 60e be made stronger ?

Nothing from the 4l60e fits the 4l80e..
Many around here run built 4l60e's from the sponsors on the right hand side >>>>>>>

Honestly I dont think youll have any trouble out of it if your modding your 5.3 and stalling it.

Ive been running a stock 60e with a vette servo and cooler for over a year behind my 6.0 with the mods in my sig. trans is still solid and I ABUSE it almost daily. with ZERO Torque management in the tune

My mods aren't as extensive... but my truck is heavy and I've been killing it everyday for the 4 years I've owned it. Bought it with 50,xxx it has 140,xxx I've never changed tranny fluid or anything still looks good, and smells fine.

when your serious, and spent a few thousands already F-in around with several builders, then you'll say F-It and go with the 80e. It will take time, you will get here soon if your making any real power at all. IMO

FWIW I bought a bad 80e when I did my swap, and its still driving to this day after towing a burban cross country for 3000 miles, then put another 2400 on it here, and it still runs muchoo stronger than any 60e I have had. Minus no reverse and the slip out of overdrive in 4th.

That said you must get a rebuilt or good unit. My experience, Ill let the GENERAL build it. Im going to be purchasing 1 out of a 2006 van 2500 with about 30K on it, then adding my converter, and calling it good.

When builders go into the trans, normally tons of **** get out of spec, its not just go in and slap it together. Gm has tolerances and procedures. I would opp for a nice original unit, 60e or 80e your preference. If you have any plans at all for more hp then the 80e in inevitable. Take it with a grain of salt.

^^^^^ Dont forget to add a Transgo shift kit and she should take all you will throw at it. ( 80e) The stock 80E BW high energy clutches are power holding ****'s.
