$5k is really steep bro

 

Id give the guys at RPM Transmissions a call, and see what they can do for ya.

 

Bought a monster in a box kit from monstertransmissions.com and got a local guy to do the bench job for me. Pulled the tranny and reinstalled it myself. whole deal cost me 1200 bucks.

 

performabuilt level 2 WITH converter for about $2000 no core charge. Actually would have gotten $75 or $175 back if i sent it back with his packaging... wish I did looking back...
Supposedly good til 750hp. Not even close to testing that limit tho.
