47re trans Torque Converter lock/unlock
#11
This is my first post, but I just wanted to add that my truck has been having the converter lock-up/non lock up problem for a while now. I was just about to plan on taking it to a shop when today i found this thread. I did what was said with the foil and tape on the said ground wire and it fixed the problem!! Im almost speechless. Im soo happy this was such a cheap and easy fix to what I thought was going to be a major repair. Thanks guys!!!

mostly noticable in OD if fells like an extra gear and basically locks the engine to the drive shaft eliminating converter slip, if you are crusing at hwy speeds it should be locked and if you rool into the throttle, it will release and the rpm's will raise slightly, but nowhere near like a down shift
if you could quickly clarify this issue with an answer to this 1 question.
so when you are cruising down the highway it should or should not slip a little when you push the throttle down?

You sir, are a gentleman! Thank you for sharing your great find!
I have a 2000 Ram 2500/ Cummins truck with about 65000miles on it and just started having these same issues where the truck would go into OD/lockup at the normal 50mph and if you floated between 48 and 53mph, it would jump out of lockup at a rate of once per 1-2 seconds, until you got to 54+mph.
I followed the electro static discharge (shielding) instructions and relocated the harness to the top of the alternator bracket. Test drove and guess what????
SMILED!!!!!!!!!!!!!!!!!!!!!!!!!!!!
THanks again!

I went through hell with my 98 dodge 24v So after the noise filter one week later it came back? I added grounds all over the truck it help but did not do it.
The real fix was $100 reflash with the upgraded program to my computer they have a new program that can handle a wider range of voltages that my alternatore was producing its been 6 mo and lots of miles problem free.

I think I'm having the same problem but I'm not sure... 2000 2500 Cummins
My issue will happen anywhere from about 35-60. The RPM jump about 100 and then back down in the blink of an eye. Sometimes it will do it a lot, other times it won't do it at all. If I hover in the 40 mpg range, it does it quit frequently.
I just picked up this truck 3 days ago. Everything else feels fine. The battery posts have quite a bit of corrosion. I'm sure this is contributing to the problem.
Am I correct to assume the issue I have is this lock-unlock problem?
EDIT: On a hunch I decided to go grab some renoylds wrap and electrical tape and did this idea. Also zip-tied the cable to the bracket off the alternator. I covered about 10" or so and taped around it. Test drove on the highway right at 55, made sure I went down the same roads it did i before and varied my speed like it usually did. On the short drive, it did NOT "skip". We will see tomorrow if it does it again. If not I hope I solved this little issue. Otherwise this truck is everything I've ever dreamed about and more.

My problem got worse when I put on the head lifgts, AC, and crues control set at 40-55 RPM would jump all over the place.
Just a FYI didnt read it all but read enough to throw caution to the wind of wy fix!
