Hello everyone..i have a 1980 cf motorhome with what i'm guessing is the original slant engine..my problem is the bearings in the gearbox are stuffed and my mechanic is struggling to find parts so i'm wondering if there is another gearbox i can swap into it without to much modification and expence that would be better for a van this size and which would be better v6, v8 ..4 speed, 5 speed.. manual or auto lol
Any suggestions would be greatly appreciated as i'm quite a way out of my depth with this one?
TIA

Which transmission is fitted now? A photo side view from underneath may be easiest. Also, the chassis number will help.

Chassis number is of the form 97360GV600001 for 1980 models and should be on the registration document as well as the small SPI (service parts information) plate attached to the passenger door frame (lock side) or vertical panel to the side of the passenger foot well (chassis cowl models) -

Looks like you have a Holden WB manual transmission which normally is bolted on the back of the Holden 3.3 litre when fitted to CF models.

The only other transmission that I know of is the Trimatic automatic transmission which also is peculiar to Holden Australia.

The only thing in common with Luton built CFs is 97760 designation (3500kg GVW chassis cab with petrol engine) and year code J for 1979 production year. Other information on Holden kit is a mystery: there is very little this side of the pond.

Converting to automatic from manual transmission requires the flex plate and torque converter to replace the flywheel and clutch, the gear shift console, rods and linkage for automatic, propellor shaft front end the right length and speedometer drive cable. A transmission oil cooler also will be needed.
