It has been awhile since I logged in but I had a few tranny bugs to work out in Feb. The TH400 was not shifting between 2-3. After a little research, I change modulator hoses, checked vacuum and finally removed the modulator valve to see if it was stuck. It was okay and refilled with fluid and did a test run. No dice. So a weekend or two later, I pulled the governor to see if the weights were sticking and it seemed okay, so I reinstalled. I filled the tranny back up and it shifts great now through all the gears. I guess the tranny sitting dry for a few months caused the gov to stick.
Now a few months have passed and I have not had time to take the rig to the dirt for real testing. I am sure there are more bugs to work out before a big trip. I hope to go soon.
