Our brand new Pre-Programmed TCM comes with your choice of either OEM factory calibrations or our Enhanced Calibrations. 

Benefits of our Enhanced TCM include:

  • Improved throttle response.
  • Revised shift strategies for better shift rpm and quality.
  • Improved Torque converter lock-up.
  • Increase MPGs.
  • Extend transmission life.
  • Works with factory or aftermarket ECM programming.  

 This plug and play TCM is delivered right to your door and takes roughly 5 minutes to install.

No dealer visit.  

No core required. 

Lifetime Warranty

 

The A50 Transmission Control Module found in the 2009-2015 2500/3500 Duramax is prone to failure. The internal circuit board fails and is not serviceable.  When this failure occurs you may observe messages such as Range Shift Inhibited, Service Brake System, Service stabilatrak, or might experience loss of gear shift indicator on dash, slamming into Drive or Reverse, and DTC U0101 for loss of communication with TCM.

 

 This repair at a dealership can cost upwards of $1000 and can take a couple days to get repaired.  Our TCM will have you back on the road quickly while saving you money.  Plus you'll receive a much better warranty.

Had a TCM failure that left me stranded 300 miles from home. Dan overnighted a TCM to somewhere local and I was up and running within 48 hours. Away he even communicated back and forth with me to ensure the TCM was the culprit so I didn't waste money. I went with the custom tuned version and after the trans finished learning it shifts like butter and puts the power down ten times better than before. I'll never buy from anywhere else. Quality product, easy install, excellent customer service, what else can you ask for? Only 5 stars, because 10 isn't an option.

My 2011 Duramax was broke down with a failed TCM. I found Dan's ad on YouTube for the pre programmed TCM and a description of symptoms that matched my truck's issues exactly. I ordered the performance TCM from Dan's and had it shipped overnight. It arrived at about 9am the next morning and 10 minutes later my truck was fixed without a trip to the dealer or being down for several days. I'm very happy I found it online and very impressed with the fast shipping. So far I'm very happy with the way my truck performs with the new TCM.

Update: in March I drove my truck 3500 miles round trip from Wisconsin to Daytona Florida pulling my 30' toyhauler and the TCM performed flawlessly.

My TCM started giving me issues on my 2013 Chevy Duramax. Got some quotes, $1100-1300 to replace the TCM. Luckily did some more research and found DDP’s TCM. Ordered it, plugged it in, and my truck was back in action. That simple, no BS. The tunes are great, and are the same EFI Live tunes I was running on my original TCM. If you don’t have them already, get them.
Thanks DDP

2009 GMC Sierra failed TCM at 100k miles, left me setting. Called Dans mid day Monday 4/20/20 and discussed issue. Phone rang 3 times and a real person answered that spoke English, never put on hold once. Followed up to order part the same day (30 minutes before close). Overnight shipping and the part arrived 11am 4/21/20. 5 minute install and back on the road. HIGHLY RECOMMEND!!!!

My truck lost communication with the transmission. I googled the code. Lead me to a YouTube video of Dan explaining my problem and how to fix it. I placed an order for a custom tuner TCM and received it a couple days later. Truck has shifted perfect since I plugged it in. Saved me a lot of money and trouble

100% best experience I have had with any diesel shop, online resources and online store. Called these folks up late in the day yesterday- told my sad TCM story and prior self-diagnosis.
Danny affirmed my troubleshooting and felt as I did that it probably was indeed the TCM. They took a lot of time patiently listening to my story- and helping me through a logic-flow analysis. Also- these guys answered every phone call, and every text I made- immediately. I needed it next day and they were able to send it next day- extra postage was well worth it at under $100 for me in AZ- money well spent. I just installed it, fired up the truck- and all errors are cleared, and the tranny display indicators are 100% back to normal. I have an H&S MiniMaxx tuner mostly for the delete function- and this new TCM is Plug-and-Play. Can't wait to drive it- haven't left the parking lot yet- more work to do on other items. Great product, fantastic service, honest, knowledgeable, and just plain friendly too. They are my new Go-To shop for any and all of my future dies l needs. Thanks a million Danny and Co.!!! @dansdieselperformance.com

TCM took a shit and left me stranded in the middle of the road. Called JD May 29th at 1 PM and ordered it for overnight delivery and the computer was on my doorstep at 9:31 AM exactly the next day. Performs remarkable and would recommend to anyone who needs a TCM. Will definitely be a repeat customer for other performance mods.

TCM went on a Friday morning and it was programmed and shipped within just a few hours. Plugged it in, cleared my current codes and the new module performed perfectly. Shifting is almost unnoticeable while driving and accelerating during normal operation it’s so smooth. Can’t wait buy more DDP products!

I made the call yesterday around 2pm. Today I received the new TCM before 10am as promised. After a 3 minute install, my truck is running perfectly. I was hesitant to pull the trigger just incase I had a possible wiring short. After a brief conversation with Dan's, we narrowed down my symptoms to be 99% a bad TCM. It was the right choice! Thanks for the expert knowledge and quality replacement part. The shipping was lightning fast!
