I believe that before we even go so deep into the control modules, the very basic troubleshooting checks should be the electrical connectors (bad and oxidized electrical contacts), which can cause delayed or failed shift solenoid operation. Always follow the repair flowchart from the most economical then work your way down to the more costly ones. Without Prejudice to anyone, this is my way of troubleshooting any repairs. Thanks for reading.

I've been trying to figure out why my jeep isn't shifting out of first gear. This video was very useful, appreciate you for this one.

Thank you I’ve been having transmission problems with my 2007 Nissan Maxima SE not shifting and not running good but definitely there’s a problem with the TCM on my dash I noticed that when I shift the gears into Park or Neutral not showing on my dash but the Reverse and Drive are showing unbelievable how something like this will not let your vehicle run good and transmission performance horrible.

I have 2013 charger that had a front wiring harness replacement. It shifted fine going over to the garage, harness was replaced wouldn't shift right after that. Codes up the ying yang clear the codes and sometimes it shift's sometimes no it wont shift right.
The garage says its a speed sensor 1900 dollars to fix, i think someone is full of it. Like i said shifted fine before a harness replacement, something doesn't smell right, i could be wrong but though

I have a 2018 Silverado 1500 no lights on the dashboard but shifting 1st gear only everything works fine. Could it be the tcm that needs to be replaced. Thanks

I have no engine light but transmission is not going into gear. I have a 48re transmission in a 5.9 cummins. Any ideas?

Great information, however a link or follow up video on how to reset the TCM or match up the serial numbers would be helpful.

08 ford fusion 4 cyl (257k) never had trans issues minus leaks and previous owner changed all shift solenoids prior to purchase.services always kept up on fluid looks brand new out the bottle

When sitting in a parking lot or at idle at operating temperature for about 12-15 minutes go for a drive car will shift extremely hard into every single gear violently making the car shake like the trans was on its way out

shut the car off and start it right back up shifts perfectly fine and as it’s suppose too smooths shifts no jerks slips etc

Assuming the tcm is on its way out since under normal conditions it’s completely fine until you sit at idle for a bit

There is a problem with the Rx350 2007 transmission. When the engine is cold, it cannot move forward, but reverse runs smoothly, and after the engine heats up, it can move forward without any major problems. What is the problem?

I am getting a P0717 Code for my trans, which occurred after I power washed the engine bay. The trans is sticking in first gear, clunking at a stop or when I let my foot off the brake after coming to a stop. I am receiving a "Service Transmission" indication on the dash, and a "Service Stabilitrak and Traction Control, " too. The TCM is located on top of the trans and connected to the gear shift selector. Everyone says my trans is done (at 200K miles), but I don't believe it because serviced the trans when required so, I don't think its the trans but the TCM. I have a 2014 Chevrolet Cruze Turbo Diesel with at AF40-6 6-spd AT trans. HELP! I don't want to replace the transmission, especially at $6K.. NO WAY!

My truck is a 2009 Peterbilt 335, in the mornings I turn it on and it drives great, I can drive it all day without any problem, but without turning it off, if I turn it off that's when the problem starts and it no longer wants to drive anywhere, he changed the switch, internal transmission ignition switch, speed sensors and the internal wiring of the transmission and the issue does not disappear, do you think it is the TCM?

My truck was doing fine up until I used a hypertech tuner on it. Now it's acting like the torque converter is going out. I've already turned it back to the stock program.

I have an automatic 2010 mazda 3 which started jerking when shifting through the gears. i changed the ATF and it still continued and later on the car lost power while i was driving and it wouldnt engage any gear. The mechanic says i need to change my gear box and tcm. While all this was happening i never had any warning lights come on. Any thoughts or comments ?

Thank you my truck battery died and the check engine light came on. Had it check and the code popped up saying it was the transmission control module

[colubrinedeucecreative]

Any particular models? I am finding 2000s fords all the time with bad trans for sale for junk prices. I would guess they are Mazda most likely. But what is a reprogram going to cost as well?

I HAVE A 2014 6L90 THAT I JUST REBUILD AND NOW IT DRIVES AND CHANGES GEARS GOOD BUT AFTER A WHILE OF DRIVING WHEN I STOP IT WILL STOP PULLING IN FORWARD AND REVERSE WHEN I TURN THE VAN OFF AND BACK ON IT DRIVES CORRECTLY UNTIL I STOP
PLEASE HELP

I have a 2017 mitsubishi lancer with a P2719 code. I've read about people replacing valves, valve body, fluid filters etc.. then having the same issue until thier TCM or ECU software was updated from Mitsubishi. Any insight into this?

I found1 video on YouTube but it was in a different language unfortunately, so it didn't help me much.
