- This video is how we fixed our push pad shifter i in our 1995 coachman motorhome that wasn’t lighting up. This is a WTECII md3060 Allison 6 speed transmission. The engine wouldn’t start, we were able to get it running by heating it at first which we narrowed down to a bad capacitor labeled
N3p
1
50v
Once we replaced the capacitor it would light up and start but wouldn’t shift into gear which was caused by a break in the ribbon connector from the computer to the push pad, so we soldered our own wires on to bypass the bad wires in the ribbon connector.
Codes we were getting were 3500, 6932, 2312
To read codes hold up and down at the same time it will read D1 and the first code, push mode and it will go to D2 for the second code and so on. To clear codes hold the mode button until it beeps twice and returns to neutral.
Do you happen to have the part number off that controller? Someone stole the push pad out of my fire truck and I have no idea what the part number is to buy a replacement. They seem to have a bunch that work on the MD3060PR but I assume they are all different. TIA!
I do not sorry, I no longer have the motorhome
Hey has anyone had an issue on a DP where you have to push D more than once to get it into drive? Like it will light up and say it's in drive with the red light next to D but it doesn't shift the first time - Is this a simple fix?
This video saved me around a thousand dollars. Soldered in a new capacitor, runs and shifts like a champ.
Thank you for sharing this. Heating my ECU did indeed enable the RV to start. I've been working for probably 10-15 hours to try to trace down electrical problems and narrowed it to the ECU but never would have known about the capacitor issues. Thanks!
This is amazing. I have a problem with the display coming on when it's cold. Today it was really bad and now I know what's wrong.
Very good info, thank you. Kindly, ....I have to ask. My eight point three alison is probably identical to yours having the same issue.. Before it was start and I assumed the batteries were still adequate. Tried with a jumper box and i'm still getting a zero when I hit start... Turn the key on and everything. Powers up low air buzzer and then. As soon as I try to start everything goes dead.. Had the same identified issues. Involving the allison no shift... At that point eventually. It would go into year and it always started.... Haven't started it for almost a year... Was assuming it was a battery issue. But charge them up and even had a jumpbox, still no start... So then after seeing yours. I might assume that it is going back to this shifter issue.. I'm really not capable to do that kind of repair.... Give me a New control box or pad or something. But I sure is that can't sit in the middle of the road. Trying to hit reverse or get out of a gas station when it won't go into drive.. Who needs that stress?
I just repaired my control panel using this video as a guide. Mine had the same defective capacitor which I replaced with a similar but different rating. Seems to work just fine. With the ignition on and the keyboard flashing, I only had to hold the capacitor with my thumb and forefinger for a few seconds and it quit flashing. No other components would respond. A hair dryer or similar was not required in my case.
Thanks to this video, I was able to successively repair my control panel. No other RUclips video addressed the problem with enough detail to be helpful.
How did you removed the keypad?
Thank you very much! This video gave me courage to open the box to fix the problem, saving me thousands of dollars. TCM failed in the middle of nowhere, wife and I tore apart over twenty items in the hunt for a capacitor and finally found the exact match in a ryobi battery charger and it has been working great. FYI this video was hard to find, you might want to add WTEC 2 failure in the title to reach more people. Thanks again!
Awesome glad it helped, and thanks I’ll add that to the description
When you say "start the engine" are you meaning the engine would not crank over or the engine would crank over but not fire?
No crank.
I really do appreciate you opening this controller up, video taping and posting it to RUclips. There is so little service information available and the price of these components/scarcity of them make it very intimidating to open up and try figure out. My father-in-law had this same problem and we found a great guy on line to fix it fast by shipping the controller to him, but it cost in $500. Now I have a diesel pusher with the same controller and before I take my family cross country, I will save this video and buy some capacitors and ribbon cable! I owe you a steak dinner for this information, thanks again!
Glad I could help, I know the feeling seeing how much these cost with little information online, I also found someone who repairs them for that price, might have been the same person. I was planning to send it to them which I still think is a decent deal compared to the price of these things, but I figured if I’m gonna ship it off to be repaired I might as well have a go at it myself trying to fix it
thanks for that video bro it was VERY helpful,,im a RV tech but dont know a thing about transmissions,,im trying to help an elderly friend of mine and boy was i stuck...Her husband passed and she needs MH out by the end of December,,,,so THANKS A MILLION FOR THE VIDEOim gonna try what you showed and God willing i will have that thing outa there before the end of the year...GREAT JOB!
sniper001353 no problem, this gave me a good headache to figure out haha hope u get it going
@@N8sk8bus thanks
Hello my friend. I have the same one and it hangs after 4 minutes. There is a piece that says 41113 T06 on it. I suspected it but could not find this piece. do you know?
Good work that was exactly the way to do it whatever it takes to get it running shows Ingenuity for sure
I wonder is there is a down grade from this system. Something simpler maybe.....
Great 👍 job!
is that the only computer the 3060 has or is there another one?
I think but I’m not positive, this was a year ago and I sold the rv since
Ruby Lover I believe there is just 1 ecu, I had a data link problem as well because the ribbon wire was internally broken connecting the push button circuit board to the main ecu, that’s why I soldered new wires in, hope that helps
Ruby Lover no just the one under the push pad selector is the only one I’m aware of, that’s where all my problems were
Good info. Hoe did you separate the board from the case on the push pad? I have the film with the buttons to replace but those compression washers do not want to budge.
