The transmission in my 1989 Turbo Diesel 90 (19J engine / LT77 transmission with E-suffix) is jammed in reverse ? which occurred within 30 miles of getting the clutch and flywheel replaced. The shift-lever now moves freely (to the point where I hit my hand against the bulkhead) but is completely disconnected from the transmission. Truck will drive backwards.
- (1) I assume the most likely cause is a broken linkage, but is there any way to tell if it is an issue with the internal gearing without disassembly? Given the timing, I?d suspect a possible clutch mis-installation of some kind, but shifting was working as well as it ever has until it locked up at the gas station. Previously, truck was occasionally very difficult to get into first and occasionally third gear.
- (2) Given my experience with this truck thus far, I am willing to spend more for increased reliability. What is the difference in labor time/costs between dropping the transmission to get at the linkage cables versus swapping in something like a remanufactured Ashcroft ?stumpy? R380? (Obviously, there is the cost of the new transmission itself, but I am largely willing to disregard that as this path would enable an upgraded-engine option at some point in the future.)
