Almost five years later...

The circulation tank heater worked well for the engine until the plug that connects the cord to the heater burnt out. I have to take it apart one day soon to try to fix the problem. I will probably solder up a permanent cord.

The transaxle heater worked OK but I just noticed that I had hooked it up wrong and most of the hot coolant was going through the radiator. D'oh! Kind of a vaudevillian outcome. The tank is furiously heating up the coolant and the rad is furiously cooling it off.

I'm going to reroute the hose to splice in at the top of the circuit, bypassing the rad. When I originally installed it, I spliced it into one of the coolant hoses near the bottom of the tranny expecting the hot coolant to flow upward into the passage. I now think that exactly the opposite was happening.

I just replaced the WS transaxle fluid with Redline D6-ATF which is fully synthetic and has better cold weather performance than WS.

I originally thought I put in T-IV when I installed the tranny but the leftover bottle I have was WS. Oddly it mentions T-IV on the label as though it IS T-IV. Anyway, 160,000 KMs and it was still red, if a bit murky.
