Im not sure on the stall. It came with a kit i bought, all the invoice says is dpc drm1 low stall converter. This problem may have started after converter install, i changed the turbo after 1st trip with new trans and noticed problem when i tried to get my 5th wheel back in my yard which is a slight incline.

It is the 3:54(55) rear end. We are about 4700ft. I think i will install my hy turbo and see if it makes a difference, that is a free and easy swap and that seems to be when the problem started. I only changed it to try and lower egts but no with the adrenaline they are under control.

I can hook up my scanner and check. That would make sense. Not sure why in reverse only but it is worth a try.

So i have the hx installed now. This problem seemed to evolve when i switched from the hy i think. I was thinkin hy would spool better due to smaller housing. May be something in trans but don't understand why just with weight.

In reverse under load rpms will not go above about 1200 and lots of black smoke. Rpm does not increase and engine does not stall. It just bogs down. Trans has a couple thousand miles on it with a single billet DPC converter, has no issues other than no reverse power with a load. Go just fine in reverse unloaded. Have had problem with 3 different trailer of various weights. Not sure where to go from here.

I use manual first all the time, there is no slippage. I pull a 12k pound trailer and start out in manual first and reach 30+ lbs of boost with no issues. It just won't push a trailer up a hill in reverse. I don't get it. I was ready to give up on this truck last year and decided to install the adrenaline now I'm second guessing that decision.

So the issue I'm having is i have no power in reverse, not transmission problem power but my truck will not push my 5th wheel trailer in reverse up an incline, just black smoke. So ever since i changed to an HX35 turbo and a lower stall torque converter this has been an issue. My thinking on this problem is the lower stall converter is not allowing the engine to increase in rpm to get any boost from the turbo. So question is, will my old hy35 spool better with this setup or would a stock or higher stall converter be a better option or am i just missing something?

Prior to having my injectors set to 320BAR i had changed the nozzles myself i thought it ran ok but did notice a slight rough idle, rough running at high RPMs while towing and high EGTs, after having the injectors built and set at 320 the truck idles very smooth and has no high RPM or EGT issues. My injectors had just over 100k miles and im pretty sure they were well below recommended pressures.

With this setup are you able to use the braking feature? I am picking up a 351ve tomorrow.

I'll keep that in mind. Thanks.

Nice. I am an Aircraft Electrician for the Air Force, that would be a pretty simple project, I could build the harnesses and do the soldering.

DoubleTrouble this explains it well

Only tuner ever used was the superchips and it had no high idle feature. It works now, just a fluke thing I guess.

Interesting. This truck has only seen winter the last 2 years of its life. My grandparents wintered in southern Arizona up until my grandpa couldn't drive anymore. I don't use it much during the winter either, I mainly use it to tow my 5th wheel and a couple dump runs here and there. It has never had an ECM re-flash, like I said I have done all maintenance since new. Only has 126k miles.
