Lock up? Affirmative!

Time to wire? Ten minutes, sir!

Just got it working this morning. This is a temporary set up with no "ghost" resisitor to fool the ECT. I just cut the TC lockup wire, found a 12V+ to power it and put a momentary micro switch in to complete the circuit.

First impressions:

There was a rumbling sound the first time I switched it on. I was in 3rd doing about 30 mph. At first I thought this was the TCC slipping but it turns out it was the engine rumbling from being at too low an rpm for the gear. When I tried it again I downshifted to 2nd and it was great. Solid and smooth. I miss that direct connection you get with a standard tranny, now I has it.

Now I need a tach to learn the shift points because I can't hear the engine.

This will work better with the full control for sure because the gear chosen by the ect is too high for the TC to be locked. I may be able to make it work better by adjusting the downshift cable. Will have to try that out later.

For now it will stay a momentary switch.
