I have an 01 Ram 3500. I bought it with a bad trans.

I bought an “425hp” kit from Power Driven Diesel. Seemed like it had a lot of parts to fix some of the major issues, but no billet shafts as I’m at the stock power level. I also added a low stall billet cover single disc converter from them.

Local builder with a great reputation put it together for me a little over a year ago. Recently the 2-1 downshift has started sounding a little rough on occasion and having a pause or hard downshift.

Yesterday while driving it wouldn’t go into overdrive. Once I got to my destination I went from R to D, at a stop, at idle and it sounded very bad, and basically does nothing now except in 1 and R.

What did I destroy? Is it salvageable or am I back at square one? Any advice other than to throw this pile away? I’m super bummed at how fragile this thing seems to be despite everyone on the internet saying “build the auto”

Thanks in advance.

you have 1st when shifted into "D" or "Low" (1st gear via shifter all way down)?

"Low" and Reverse uses the rear band. The trans gets it's 1st gear without the rear band when shifted in "D"

Let us know, as this helps narrow down on what may be going on.

Trans does noting in D, but in 1 it will attempt to move, but still feels locked up or in a higher gear than 1 as it really struggles to move.

All gears pull the RPMS down, but the truck wont move. verified its not the converter bolts today.

This happens a lot when you bring parts to a shop. No warranty.
If you aren’t going to do it yourself, just buy the built transmission. Or even a oem replacement.

I understand, I knew the risk. I wouldn’t have bought the parts if I hadn’t intended to do the work. I just got too busy with work and life.

As a side note, after doing some reading I believe I broke the overrunning clutch aka sprag.
