That's how to fix limp mode?

Diane & Paul finally discover what caused Diane’s transmission to stick in 2nd gear (limp mode), as well as discovering how to fix it. Watch as they find the transmission control module (TCM) and eventually learn what caused limp mode and how to prevent it from happening again in the future. She has a 722.6 transmission.

Isn't it great when it's a loose connection? Good video. You two are great. Love you two.

Guys get yourself an impact and sockets it’s life changing 😂 I was doing everything by hand untill a few days ago

I would test the TCM for an intermittent connection. Can you drive the car with the floor board off and the module exposed? Then you can tap on the module, wiggle the wires/connectors, press on the module while driving and see if you can recreate the condition. It could be a bad internal solder connection. Maybe it fails when the module gets warm. How expensive is a replacement module? Thank you for the update! I enjoy your videos! God bless!

its most likely dirt on grin with the grease that is binding up the track and gears on the seat... it probably would be easiest to take out the seat to fix it... there should only be like 4 bolts holding it down.. just remember the connectors. when pulling out the seat... I would use like WD40 or something else to help clean off the grease.. also could be used on motor too if its seized (hopefully would fix it) but most likely the gears are seized and stop being able to move... I would get some lithium grease or black grease to put on tack... and get a box of que tips and roller of paper towels.. might want to pick up cotton balls and makeup pads they are stiff and might help you clean... if you got a dollar tree near you.. you can pick them all up for a $1.25 each.. if that doesn't fix it... I would check to make sure that your getting power to it.. if you take the seat out you can put it on bench or grown and diag it and clean it.. should take like 20 mins to fix it... PS also get some gloves because you will be throwing them away afterwords

I just remembered, my sister bought a VW Jetta back in the 80's and it would stall when she pressed the clutch pedal down. It wouldn't stall for anybody else! Just when she was going down the road and upshifting. Many dealer visits. Nobody could figure it out for a long time.

Eventually, a dealer mechanic found the loose ground wire. Apparently the way she stabbed at the clutch pedal made the engine rock hard enough to shake that ground wire free and then something else (probably ignition related) lost interest.

I forget if you've fixed the power seat yet. Kent Bergsman has an online course (for a few bucks) about diagnosing and repairing Mercedes power seats. I don't know if it applies to your generation but it just might.

Let's not jump to conclusions! Are we sure we can't find a way to blame the stereo installer? Are we sure there's not a 3M Scotchlok power tap hiding in there somewhere?

Is the transmission control module bumping into the stereo amp when the aluminum floor board flexes? Could you build an extra layer of floorboard out of wood to go on top of the aluminum and take the foot load better?

Also, some car electronics nerds swear by a product called Stabilant when it comes to mystery issues on connectors/pins.
