got it pulled out today. going to start my rebuild tomorrow. ordered a monster in a box with a reverse input drum. going to take a bunch of pics.

 

A friend at work got a Monster in a box kit for the 4L60E in his Silverado. He rebuilt it last year and has been very happy with it. Said the parts kit was very complete, and the stuff was high quality. His came with an instructional DVD (don't know if he paid extra for it) he said it was really well done and walks you right through the whole process.
In the end, he says it shifts great, firmer than stock, and much stronger.

 

You get the servo instructions you were looking for?
I tried in vain looking the other day.

 

it does have everything in it. i also ordered the reverse input drum for the new band and it came preassembled with the piston and spring assembly already.

yes sir i did Dana at probuilt sent it to me.

 

well found the 3-4 clutches burnt. but also found this. need to know what caused this.




its the over run clutch spring and over run drive gear.
