Not really a product as such, but I did the Suncoast APPS rewire and it took care of my converter lock-up issues.

Wrap the black and tan wire going from the alternator to the passenger battery in aluminum foil. Solved the problem on my stock tranny. When I got my dtt I got their noise filter and that solved the problem permanently.

Don't beleive there is a one fix cures all repair. Suggest starting with grounds and power connections. Clean rust and seal with grease.
Next have batteries individually tested at parts store and have alternator bench tested. A inspection of brushes for grease on slip rings would be in order while off.
Try shielding the wiring at alternator. Wrap aluminim foil around wiring for 18 inches of so, back toward engine. Taking tape and couvlute off and wraping alternator wires (3)with very small wire for 18 inches or so and then ground this shielding wire. Do Not short the shielding wire to alternator wiring. You can now rewap the convlute for nice apperance.
Some other items of intrest. APPS reset mayh be of benefit. Killing memory by disconneting all battery terminals and toughing a positive lead to a negative. You are shorting the wiring, NOT the batteries. This kills memories and fault codes.
A poorly adjsusted brake switch or erratic speed sensor need mentioning as a possibility.
A condenser (radio supression condenser from old Chrysler ignition coil) housing mounted to alternator frame with the lead connected to alt. output terminal is effective in reducing alternator stator wiring imbalance and internal condenser issues.
These are very low cost repairs and have been effective. The tranny specialist also offer various supression fixes and rewiring kits, but are expensive in most cases. Some have success with kits and some don't seem to, is my take on them.
A worn out torque converter may be the culprit also.

Sure there's a fix to it.

TC switch howto (with pics)

Cheap, simple, and it works.

I had problems also and the combination of wrappin the alternator wire ,apps reset,and cleanin gounds have cured mine SO FAR.but thanks for the posts

jadog · 07-19-2009, 11:48 PM

have your batteries checked. they have to be in good condition. even if your truck starts fine one could be marginal and cause problems. batteries are big noise filters. electrical noise is what causes these trans.tc problems. this is what i as told by Bill owner of DTT transmissions. it worked for me, it might for you. also a noise filter from DTT.

My new problem is that my tc basically does not lock upo at all any more. Any speed any rpm i can rev the engine up and have to wait for the trans to catch up. Espically when towing. I am planning on putting a G56 trans in soon enough I just need this trans to hold up long enough for m to get everything together for the swap.

dieselstud27 · 07-21-2009, 11:45 PM

the instructions from the ats link don't work on my truck. The only thing that it did was keep my transmission from going into overdrive...I'm thinking about trying the suncoast one tomorrow to see if it works.
