Good Morning
I was in the process of changing my transmission filter and putting a new gasket on the pan and I noticed that the wire for the down shift solenoid was all cracked, partially bare and nearly broken off at the solenoid. I bought a new one from Napa, part # TKS100 per the parts interchange book and it's not even a close match to the one I removed. Can anyone shed any light on what is the right one for replacement. I've searched the net and the only one I can find is the one that doesn't match.

Thanks
Ray

As Gene Fisher said, Manny recommends not using the solenoid. Just downshift manually when you need to - keeps more pressure on clutches I think.

IIRC manny does more than just unplug the solenoid. I think he blocks some passages to prevent internal pressure dropping leaks. Check with Manny.

Ray - if you want to repair the old one there is some tefflon coated wire somewhere in the barn. It may be with the wire stuff on the drivers side of the coarch, in a desk drawer or in one of the "automotive electric" blue tubs in the lower garage. All the soldering stuff is in the IBM cabinet in the lower garage.

Here are the pictures of the WRONG and the CORRECT transmission
downshift solenoids.
