Tcc? O/d? Lock Unlock Fix?

pro99 · 07-08-2007, 04:52 PM

This is a poll to see what helped you fix your TCC? O/D? LOCK UNLOCK concern. I see a lot of post here asking about this but not a leading fix for it so I thought I would do a poll for them that are asking. With that said what fixed your TCC, O/D Locking Unlocking concern?

Thanks for taking the time to vote

The only thing that worked for me was the Happi box filter. I tried everything else and the dealership also gave up on it. I tried the filter and its been great for the past couple of years.

Definitely try a Noise Isolator, we sell tons of them and for the price it is definitly the thing to try first. 8 out of 10 times it is the fix for us.

All I did was take the ground connector to the PCM on the firewall apart and clean the connection, No problems for almost 2 years. I was told this trick by a friend that works on the heavy line at a Dodge Dealership in Phoenix AZ. 98 24 Valve 1 ton Dually

Yep, worked for me too. Ran a ground from the PCM to the negative terminal and wrapped the wire from the alternator to the battery with that aluminum furnace tape. So Far so good!

What part of the pcm did you run the ground from.

I ran the ground from the PCM case. I loosened a screw from the rectangular that attaches to the firewall and tapped in there. It's still working. Not sure which one fixed it, but it did.

i did it ALL except buying a noise filter from an aftermarket source

Remove engine harness and install braided noise sheilding on TPS wires from TPS to PCM and on Trans control wires from Trans to PCM. (this precludes the need for a noise filter since the braided sheilding prevents the noise from entering the wires intially)

Ground PCM case w/ 8awg fine-strand cable to negative battery ground

Replace Ground cables on battery

Replace Gov Press sensor and Gov solenoid

Replace trans fluid and filter

Replace Output shaft speed sensor

Remanufacture PCM

Rebuild Generator.

my Gov sensor/solenoid were faulty and that got my PCM out of limp and allowed it to shift normally. however, nighttime driving made the TC lockup, OD/D shifting problem apparant. i knew it was dependant on electrical load since it only happened at night, when running the lighting increased the Generator load dramatically. turns out the brush in the generator was worn down to the shoe and was arcing out on the armature. this acring created RFI which was introduced into the harness and the PCM via inductance. replacing this brush (even though my truck produced 14v while running and showed no evident signs of failure) solved my shifting problems 100% . my truck is now shifts as strongly, predictably and reliably as it did when it first rolled of the Lot.

Moral of the story; REBUILD YOUR GENERATOR FIRST, before buying ANYTHING else.
