Got it changed.. stuck a 195 in it. The old one had weaker springs, and was still a bit open when i took it out. So that must've been my problem. One thing I don't understand is how it can be stuck open. I can think it'd we worn, and refusing to open against the strong springs. Guess I don't understand thermostats good enough.
I did a coolant change, and pretty well flushed my engine out. Stuck a hose into the upper engine hose, and ran water thru the engine. Prolly did not get everywheres, but just as long as I could get it thru the block.
This morning, It was chilly. I let the car warm up for 5 mins. Got in, and the darned thing was blowing HOT air!!
Never thought it'd be a BIG improvement. Seems like it'll be nice this winter!
Well, started driving, went to 80 kph. Tranny shifted into OD. Another second, and the torque converter clutch engaged, and she ran good. Did not disengage at all. So far, so good.
Most of my kms are highway, or country, so having the TCC working is a big plus. This was only my first run. I don't know about later, but it should run good.
Thanks for the help!
