Harry, I take it by your question that you are looking for a little more speed and/or lower engine rpm? Possibly for the runs to and from Kelowna? Rather than spend a lot of time and money altering your CMP by retro-fitting a CCKW or any other transmission for that matter have you considered any of the many available bolt-on electrically operated overdrives? I seem to remember back in high school my friend's Humber had such an overdive...a Laycock de Normanville unit if memory serves me correctly. In the modern era, there are many heavier duty after market overdives available for RV's which became popular when fuel prices began to rise. Although it would require shortening of the drive shaft, it would leave your truck original and cost less than a tranny swap. Something to consider. Derek.

Default A new truck

I'm not going to put it in my C15A, as it runs real well with the 235 and now the 10.50 16's from Wallace Wade.
I might add a flexible aluminum fan but that is about it for mods. I've put almost 13,000 km's on it so far.
No, what I've got now is a recently rebuilt 270 and tranny from a CCKW that I'm going to put in iether a C60X or the C60L in my driveway.
If I do the C60L I'm thinking of putting the differentials out of a C15A on it to again get some safe highway speed into it. I might want to take it on a long drive.
Comments welcome on the pro's and con's of the 270 Vs. a 235

Hi Harry..
The 270 is too long for the C 60 L but the 235 will fit in better..
The C 60X is set up for the 270 and will fit right in..Notice the extended grill section on any C60X ..
I guess anything will fit in anything else,but why suffer if you don't have too..

I actually heard about the extended grill but haven't actually had a first hand look at one that was still in one piece. I took some pictures of the front mount on both trucks and was wondering what I might have to do. Is it a case of the radiator having to be moved forward or the front motor mount or both. I noticed on the C60X that the rear mount is different in that it is not actually a crossmember but 2 seperate brackets on each side.
Those manuals I got off you Alex at the start have been real life savers but I don't have the C60X Books. Are there any good pics that really illustrate the differences?

Smile CCKW Gearbox

Gday Harry , i Have a cckw box in my c15 blitz wireless van and it is great on the road it keeps up with jeeps very well .

It was already fitted when i bought the vehicle so cant help out with details of the conversion but it has no speedo so i have to keep a sharp eye out for speed cameras.

Cheers Matt Baker.

That's great news. The speedo on A's L's and X's runs off the transfer case so I should work that out OK.
Since yours is, I assume a 4X2, then it was just a case of shortening the driveshaft.
