I had to give a shout Out to Allan, Frank and Ryan at Performabuilt Transmissions. I purchased a Black Edition Level 3 4L60e from them a few years ago. It worked perfect on my 815 rwhp car running mid 9s. I had a new engine built and had a thrust bearing issue on the dyno. Since it is difficult to assign the exact cause of thrust bearing failure I talked to Allan and he said to bring the tranny down it and he would have it gone through. I drove it down this week (6 hour drive) and they actually tore the entire tranny down even though it only had 7 passes on it since it was refreshed. They let me watch the tear-down at their shop and it was in perfect condition as we thought it would be. Ryan, who was doing the work then told me they have been able to obtain better clutches and other parts that make the tranny even stronger and he upgraded everything on the re-build. It took about 5 hours to do the re and re and Ryan worked through his lunch to get me on the road for my long ride home. When we are all done and I went to settle up Allan, the owner, would not take any money!! He said I was a previous customer and had some bad luck and he was happy to help out. Who does that anymore! We all experience lots of bad service but rarely do we experience some good old fashion service that includes the human equation on both sides! If you are looking for a transmission and want to know the folks who sell it stand behind it - talk to Allan or Frank at Performabuilt - they are straight up guys!!

John, not sure what you are asking?
