Jimbo, I didn't get quantities perfect. You're right, tranny is less than 2 quarts. I do recall you're supposed to measure right after turning engine off, not minutes later.
Also some confusion out there on v-drive fluid. Book calls for something special called MobilGear 626. Rick says 30W oil if I recall correctly.
Believe I cleared M1 ATF and gear oil with Jeff Dorge, the former west coast TMS rep, and both have been working well for 12 years.
