Trying to decide between RPM Lvl VI and Performa Built Lvl II. Diff of about $800 (RPM is more) when all is said and done. Both are highly recommended but RPM uses a billet output shaft and my tuner has a Lvl VI in both of his Magnacharged TBSSs & they've never missed a beat. I'm NA right now putting around 400/435 to the tires and I've already burned through two "upgrades" to the current unit. I know, I know...do the 80 swap but I want to stay away from the extra weight and I'm confident in the upgrades of late to the 60e re-build market. Plans of adding the TVS after summer so need it to handle 550+ hp/tq.

Anyone have experience with either one?

Thanks...

 

I have a TransbuilderGuy Level 5 and its rock solid. I have about 100 more hp and tq than you and with his other customers, im not even close to touching any worries or limits with this.

It is 100% worth calling him.

 

You know...I thought about him as well - just forgot to include it in the blurb. Mind if I ask about the cost of the build? Thanks for chiming in...

 

I have an FLT LVL 7 with upgrades in the classifieds. it has the billet input, billet output, sonnax drum with extra clutches, a trans-brake, deep pan, FTI converter and all the secret machine work that FLT is known for.... just incase you want as beastly of a 4l60e possible for half price

I had it built for a 500rwhp motor with a 200-250 shot on tap. never got a chance to try the trans-brake or nitrous, but it was running 1.46 60' on motor off the foot brake.

I've successfully run Performabuilt in the past too. the billet shafts and sonnax drum are a great piece of mind though

 

That a lot of transmission Would have thought you would have sold it by now at that price. Not sure I need the trans brake - she'll still be my DD after all.

 

This....i loved the transbreak on my 60

 

BUY THIS hahaha. there, that was easy

 

you never know what it will end up in next! the rossler trans brake does not affect any normal function of the 4l65e unless you wire it up and grab a button. everyone has been brain washed into thinking you need a 4l80e now days. I figure that's why it hasn't sold.

or you can pull the trans brake out and sell it to recoup some money.

 

Yeah - it seems that the quick reaction to 4l60e failure is to do the 80 swap. I have to admit I was leaning that way until my tuner, whom I trust implicitly, convinced me that there a more than a few quality 60 builders out there who can produce a comparable, lighter unit for honestly just about the same $ as would be involved in a swap when all is said and done.

 

....so did you buy txsilverado's yet? lmao
