well it seems like i will pick up the trans friday is there any problems with these. because i hear later models are better but some says an 80e is an 80e... let me know before i maake a mistake also i think it a earlier model 99 came without the top bolt hole... i will do a rebuild a shft kit once money gets right also but for now i will have this on stand by. lastly will i be able to use the p/n from the stickys to do this swap

 

Had a performabuilt for 7the months till it popped behind my 5.3l think I would jump to an 80e04sierra from the get go

 

I've got a performabuilt lev 2 but IMO just do a 80E with a shift kit and a stall and it will out live a 60E all day

 

My FLT is running flawless so far behind my heavy truck and my heavy right foot.

 

I've got an FLT level 4 backing the 5.3 for the past 160K miles with 0% TM. No problems.

It is now backing the 6.0 I just put in. Mind you, I do not take the truck to the strip, but I do get on it every now and then.

I've been very happy with the choice I made.

 

My buddy has a FLT level 7 and drives like a madman with zero problems. Don't know anyone personally that has a Performabuilt, but a guy over on silveradoss has had nothing but problems with his. He has sent pulled it, sent it back, re-installed it multiple times and last I remember still never got it sorted out. Not only did he have problems with their transmission, but also their converter too.

 

Performabuilt 80e and no issues for the 3 years of beating on it with all the different combo's I've had.
