    I was going up a pretty good incline in my 07 5.9 with the 48re and it shifted out of overdrive and wouldn’t go back into overdrive then once I got to the down hill portion of the hill it lost all gears out of no where and if I let it sit for a wile 1 and 2 will work but won’t shift out of those...

    Sorry first time poster here, so this might be a little long winded. So I bought a diy transmission build kit from Power Driven Diesel that's rated for 850whp in July of last year, had the dealership install it, and had the torque converter go out within about 1100 miles. Just recently got a...

    My 2003 dodge ram 2500 hd with the 5.9 Cummins feels like it’s suck in over drive. When I’m going 70mph my rpm’s are at about 2,900 which is way too high. Some times when I’m driving it will kick in and shift out of over drive and the rpm’s go to where they are supposed to be. What do I need to...

    I overfilled transmission by 2 quarts. This morn seemed to slip a tad then was ok. What's the deal? Should I drain it out or will it survive? Let me thank you in advance for your time in responding. Worried

    So I just acquired a 99 2500 at a great price with some damage the the harness under the fan due to a body lift causing the fan to hit the harness. I respliced all the wires with wire nuts just to see if it would crank. The truck cranked right up and ran perfect but all I have is first gear and...

    I’ve been leaking tranny fluid for a while and couldn’t find the issue but I think I’ve figured it out. It looks like it leaking out of this 90° boot. A buddy had the same issue but he said he was leaking out of the hard line labeled 1 in this picture. Those lines are going to the heat exchanger...

    Early 03 Cummins with 47re and for some reason it'll hold the gears perfectly and shift normal until like 160 ish degrees and above it then holds first until 2500 rpm or sometimes until 3000 and 2nd gear is a similar story as well but as soon as it gets to 3rd and OD it's fine. It also drops...

    Hello everyone. My truck is a 01 24v. Putting a built trans in I bought off of a buddy. The neutral safety switch and other plug on the same side however don’t match the harness on the truck. Here are some pictures below of what I am dealing with. I am quite lost and any help would be very much...
  11. 94-98 Powertrain
    I picked up a 94 12v about a year ago and have been slowing restoring it. When I bought the truck I was told about the issue of the truck not being able to lockup/go into overdrive. Sometimes it will go into over drive and it’s great but most of the time it’s about to lockup and then drops. The...

    Can only find info pertaining to second gen on this issue. Randomly sometimes it won’t shift out of second until I stop, turn off the truck and restart. im assuming it’s going into a limp mode? Has anyone had this issue with an 92 auto and found a fix? Thanks,

    Just bought a 1991 D-250, needs a trans cooler and lines. Where do I find the parts, and also what injectors would you suggest.
  17. 03-07 Powertrain
    This is my first time on here and just though I'd seek out some advice from the group. Last week I had an issue where my truck was stuck in first gear, which was the first time it happened to me. I drove it around the block and just parked it at the house. Several hours later I went to drive...

    I recently was driving my truck when I noticed the truck was revving a lot higher before shifting and slipping very bad, it then got very worse and I noticed a bad ATF leak. I found the leak, it was a transmission cooler line that had a hole rubbed into it. I had the line replaced and refilled...
