So that's why you said to use 3rd next time I flog my truck!

Will do the same from now on. Yeah my tranny has been the one thing that's never failed me in the two high HP trucks I've had it in. Still running strong and making Jake miserable everytime he drives it!!

 

Sorry to hear about your luck man. That's a terrible feeling when something goes wrong far from home.

 

mmm.... interesting, this makes me thinking, use D only driving around 0 beating on it and 3 for track and other beating on it

why would D break a transmission easier then 3?

 

Trans issues are the biggest pain with a build.. My truck has been sitting almost a full year now because i trusted a local builder to install a transgo hd2 and rebuild stock 4l80e. Turns out this so calle professional was dumber that a sack of potatoes and didnt even replace the speed sensors! (original issue on trans) instead he rebuilt the trans which im out 1500 bucks :/ then he used washers to space my converter which he also did wrong and it jump out of trans. Messed up the splines on trans and screwed up flexplate! I have left my truck sittin in the shop on jackstands for 9 months now just too agravated to touch it anymore and have been focusing on my ls1 alot more. Sux that their are so few dependable builders out there these days.. hope u get the company to do their fair part so u get back on the road

 

Exactly, and well worth the wait.

 

Youll have to get one of the trans guys in here to explain it better, but I believe it engages the overrun clutch...or something...

What ive heard is about the worst thing you can do is when you are doing a burnout, let it shift to 2nd then let off in high rpm at the top of second. I believe there is a part in the trans that turns in reverse at double speed...so bringing it from 10,000 down to 0 very quickly often breaks it.

 

Yeah thats about right. In both cases they are roller type, one way sprags that can handle quite a bit of load applied gradually...but shock load can demolish them in a hurry. The overrun clutches take the load off of the roller clutch when not in D so it adds a lot of strength. Same thing with letting off in 2nd at high rpm, but its the intermediate sprag.

 

thank you i see i need to change some actions then

 

So doing rolling burnouts in 3rd gear will prevent that from happening? Or at least make sure what Richard said doesn't happen?

 

The idea is not to let off during the burnout while its in 2nd gear.
