I have a "small" leak coming from the seal around the manual lockout shaft on my overdrive unit. I have never been into a transmission and/or an overdrive unit. From reading Randy Rundle's document the overdrive unit must be removed and the seal replaced from the inside. Other than the caution regarding spilling the clutch rollers is it a major project to replace the seal or just leave the cookie sheet under it?
Bye the way, for those of you who may have not been aware, Randy Rundle, Author of "The Official Guide To THe Borg-Warner R-10 and R-11 Overdrive" and booklet owner of Fifth Avenue Antique Auto Parts, passed away in February 2020. He helped me with the setup of my overdrive wiring and I'm sure many others. He will be missed.
