01_Cummins_4x4

@Chris O. - Congrats on making an awesome tool for troubleshooting our Dodge diesels and other OBDII vehicles!!! I just got back into diesels last Friday when I got a 99 Dodge Ram 2500 quad cab short box Cummins 4x4 pickup, otherwise I'd have been all over beta testing your tool for you before now. My Dodge is having a delayed wait to start issue and I just replaced the AIT sensor, but no change in the wait to start issue. My ABS and brake lights will come on every once in a while, and I just put in a new rear ABS sensor in the rear end, but it's still happening. It doesn't have the bad ECM code, but I'm still leery that it could be the ECM. My auto transmission is painted gold with a blue pan, so someone must have been through it, but when it shifts from 1st to 2nd, then it shifts up to 3rd and then it shifts again really quick and disrupts the normal acceleration, and then it shifts into OD. It's not slipping at all, but it is annoying as hell. Would you by chance need another tester to help improve your tester tool by providing all the data that I can get from it? I was the person on the Toyota forums that did all the testing and diagnosis for the Limited 4Runner multi mode 4x4 system, and I helped saved many Toyota owners thousands of dollars by testing the sensors of the 4wd system, instead of replacing the transfer case that the Toyota dealers were quoting them at $2k a pop. I'm an IT guy anyway, (network administrator) so I enjoy the data logging, diagnosis, and resolution of issues. Please let me know ASAP if I can be of assistance in helping improve your testing tool. Thanks, Doug

I just rebuilt my hydro boost with a seal kit because it was leaking power steering fluid. I carefully separated the halves of it and just replaced the one oil seal that sits around the piston, and then the figure 8 seal. My hydro boost was acting normally except for the P/S fluid leak up until this point. My hydro boost is not leaking power steering fluid anymore, but now when I start the pickup or I'm moving slowly, it acts like the brakes are self applied without pushing on the brake pedal, because I can give it throttle pedal pressure and it takes more power to move the pickup now. I understand that this is most likely caused by a plugged/restricted return line from the hydro boost, but is there something that I did to cause it when rebuilding the unit? Thanks, Doug

One thing that I noticed on my 99 and on my friend's 02 Rams, is that the inside of the vacuum lines can get plugged up from the rubber hoses deteriorating over the years and the vacuum line gets plugged up. We took a blow nozzle on an air hose and blew each line out until we could feel air coming through them (with them disconnected from the vacuum switch on the transfer case, as well as, them being unhooked from the actuator on the front axle. Now my 4x4 kicks in so much faster than it ever did before, and the light kicks on just as fast now.

I just took my 47re auto trans out of my 99 Cummins 4x4 and installed a NV4500. I have all the cooler lines still as I took them all off with caution because they weren't leaking and I bought the longest one from Dodge for $151 a year and half ago. Which lines do you need? The only lines that I cut were the two rubber lines that head to the trans cooler in front of the radiator on the driver's side. Let me know.

Power wise, it's like driving a different pickup. I do have a 99 ECM from a manual Cummins 3500 if I want to go through the hassle of programming my VIN into it and testing it out. Everything worked like normal before my auto to 5 speed swap, and the only wiring I did was the auto neutral safety switch 3 wires - two outside wires to 5 speed reverse light switch, and center black/white tracer wire up to one side of the CSS, and the other wire from the CSS to ground. Has anyone just used the auto PCM and not had any issues after the swap?

I just swapped out my good non-slipping 99 4x4 47re trans and installed a brand new South Bend clutch/flywheel kit, rebuilt NV4500 trans, and changed the input shaft on my 241DLD t-case. My friend entered my VIN into the PCM so there would not be any VIN mismatch codes thrown. I swapped out my auto PCM with a 99 Dodge Cummins 5 speed PCM, connected the two outer wires from the auto trans NSS to the nv4500 reverse lights switch, ran the black/white tracer center wire up to the CSS, and then grounded the 2nd wire on the CSS to the left side under the dash where there is a common ground point. I'm still using the factory auto instrument cluster and the auto trans PCM wiring harness. I pulled out my instrument cluster and removed the PRNDL shift indicator and installed the manual trans blank that goes in that spot. The only issues I have are the seat belt light goes out after starting the motor, but then it comes back on and stays on while the pickup is running. My cruise control works fine like it should, decel, accel, and set, but the cruise light on the dash does not come on now except it does come on when initially turning the key on. I haven't swapped the steering column out, still using the auto column with the shifter removed. The cruise light worked before the swap, and cruise control itself works after the 5 speed swap, but the light does not light up now on the dash.

I just got a second email this evening saying I'm in the lost member category....just thought you'd like to know.
