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

your one of the few lucky ones...

Sounds good I'll plan the 60e upgrades and if she blows my guy will rebuild it. Thanks for the info

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.

Food for though... my Stock 4.8 caused my 4l60e to take a dump....

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 shit 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 MoFo's.

Make sure you change the sunshell...they are very week
