16k level 6 built by r.p.m 4l70e awd 3200 r.p.m stall....

Kids in truck. I was very light on the throttle( still haven't put it on the dyno from the 402 build and still on break in tune) and all of a sudden it was like someone put it in neutral. Coasted into a parking lot. No fwd gears or reverse, has parking brake. No funky noises ..but I put a scope thru the inspection cover and I have fluid dripping out of the input shaft seal ... my guess is the pump failed :barf:..

Very sorry to hear...hopefully isn't too expensive!
that sucks. 80E time :)
And with only 6.5#'s of boost. I'm still running my stock converter and trans with 12#'s. You need more torque management.
Sounds like pump. Sorry to hear! Thats always no bueno when kids/wife is with you.

I wasnt even close to being in boost ! And Tq management is for pussys ! lol j/k
Check the TCM tune! I had pump failure on mine as well, but it was likely do to the tune. Make sure adaptive learning is enabled.
talk to rpm see what they can do for you. If its ahard part that went you really cant blame that on the vendor.
no blame ...i bought it from a third party

I've disabled adaptive learning on many tunes, without failure. I've been running mine like that since HPT enabled that function. I don't see a correlation between the two.

:rofl:....
It sounds like a pump rotor failure. Check the fluid level, if the pump failed the level will be way over full in park. The pump rotor is a pretty common failure on a built 4L70E running high line pressure. We have gone to all billet rotors on any supercharged, NOS or turbo vehicles because of this.

Sorry to hear about the trans Matt, unfortunately with these parts bin trucks the trans is the weakest link. Unfortunately no one at GM went "you are the weakest link, goodbye" and let them be produced with a craptastic trans. Boo
Sorry about the Trans man. That sucks but maybe it will be a simple fix.
Well it's out... From what I was told, pump has puked... ~TTT

Let me know if you need anything.
Sorry I missed this post. It has been a mad house around here this past week. Im not sure if you have called the shop yet, but even tho you bought it 3rd party we will still repair it for you. There are many things that can lead to pump failure. Converter spacing is the leading pump killer. Let me know if there is anything we can do.

Do you guys offer a freshen up service like FLT? The charge $250 for ALL labor and customer just pay for parts.

I know a guy that called and asked about this and was told NO RPM does not...

He informed you incorrectly. We do offer a refresh service on all of our automatics. It is $600.00 to refresh the transmissions. This includes labor and all soft parts (ie: clutches, bands, seals and gaskets) and if any hard parts are damaged those are extra.

Good to know! My rpm trans and Vig converter are definitely my best mods.
