I have had this post at two other sites with 0 help or knowledge put forth....I forgot this is the ONLY place where anybody knows anyhting

Anyway:
I just wasted my second BUILT trans in 3 weeks, 4th in a year. I know I could go with an 80 and all that crap, but don't want to....would rather fix the trans one more time, take everyhting off and sell it if I cant get a 65 to work.

I messed around with it today and reverse, 1st and 2nd gears work and Drive will hold for a minute, then pop out????? any ideas? Doesnt sound like total catastrophe as I initieally thought. Something broke as I could hear it snap, grind and evertything else. It sounded and felt liek the driveshaft broke and started dragging, but didn't??? I wonder if maybe the transfer case gave way...???


Thanks In Advance guys

 

Wow.....that sucks! Who is building the trans for you or are you doing it yourself?

I would go for the FLT Level 5 myself or throw in the towel and do the 80e. Mine has been holding up to the abuse I throw at it. we have similar hp#'s (without the nitrous I am ~515) and what is your fianl gear ratio?

 

This is my second local shop around here...ther were suppose to be pretty good at asssembly....I supplied all the "good" parts. I have everything in it that the FLTs have and more probably. 4.10 gears

 

Put an 80e in and be done with it a 60e isnt going to hold up to youre Hp No matter who builds it.

 

agreed. I think Vince @ FLT would tell you the same thing.

 

I agree... i went with the 80E and im not puttin even close to your numbers.. if you break the 80E you have issues.. haha

 

Get an 80E it will hold up with your hp level.

 

I would love to hear that. They sell too many with the same or more power than I am putting out.

 

I build gm transmissions and i went through 7 4l60e trannies with every combination of parts known to man before i put a 5 speed in my truck. i dont know how much power your truck is making but i can tell you that when you got on it and you heard that bang like somehthing let go it was the sprag in the input housing that rolled over. i know ive done it twice you chould be able to have it swapped out for a new borg warner one and be just fine.

 

Do you no for a fact that your tranny has more then what flt or other proven companies have in their trannys, not being a dick but a built 65 should hold up to the hp your putting down.I would pull it apart and see exactly what is in there, then try a FLT or Performabuilt tranny out. But if your planiing to make more power then maybe a 80 would be a good swap, since your in a heavier truck... Good Luck
