Hi everyone, still working on getting my 700R4 transmission ready for installation. I've read several stickys and many threads. Took some advice and contacted the transmission center who send me what was needed to convert from electronic to mechanical speedometer. That installed really well. Additionally, I also ordered a TCI lockup kit for the converter. Thats where the problem lies. If I read the directions and looked at the parts once, l did it at least a dozen times and I'm no further ahead. They call some parts by technical name and I don't have a clue which one they are referring to. Just today, I realized that I have to run power to this kit. I don't have any power going to the old one. And there's a plug that has I think 3, maybe 4 prongs that something gets hooked to. I know this has to be done so I'll just have to keep studying the schematic and directions. I do believe I'm starting to approach the level of regret for puchasing this kit. Especially, since I think it will operate without it.
