Fuller 9 speed shift pattern

marky:
It’s an RTO-9509A and the shift pattern for the four main gears (excluding crawler) is as you would expect to find in a car with 3rd and 4th swapped round.

It means basically that the gear stick does a W to go through all four gears instead of an H.

Crawler is far left and BACK, reverse is far left and FORWARD. The shift layout was normally found on the engine hump in front of the park brake controls - it will no doubt be long gone now.

I’m sure you’re right, and RTO-9509A is certainly the likeliest box for this one tobe, as the lorry pre-dates the RTX series. I’ve a vague recollection that one of the 9509 variants (maybe the 9509C) had the conventional H-pattern, just to confuse us all! I once met one like it in a Transcon c.1980.

One way to find out!!
