Description on a transmission for sale says transmission from 240 with j type overdrive. The gearbox casing has 380100 k270 k4 how can i tell if its an m41 m46 or something else? Thank you in advance

 

M41 was used on really old 1800 class volvos.

a 4 speed w/ J overdrive is almost certainly a M46

 

Thanks but I read the 75 240 had an m41 and he aint sure what year it came from

 

all the volvo gearbox numbers I can find start with 1208xxx

here's pictures of an M41 short cover and long cover version.

and here's an M46...


I note the M41 has 'X' shaped ribs, while the M46 has two each \\ and // ribs.

 

I cant figure out how to post a picture on here

 

post the picture on a photosite that allows linking (NOT photobucket... you can use imgur, I use smugmug but that costs per year, etc), then right click on the picture on that photosite, 'copy image address...', then click the photo tool in the post editor, and paste in that link.... the link should be something that ends with .jpg ...

 

 

 

thats an M41, for the P1800'S, 140 series, and was used in the 1975 240, before being superceded by the M46

ancient. also looks to be completely unrestored/refurbished.

 

Thank you for your help i needed some reassurance before I purchased it. It should bolt right in to my 122 then i think thank you again

 

I'm looking for a late M41 also called M41 1.5 which was only compatible with the J-type overdrive. I was offered one but not sure if this is it. Here are the pics with the relevant numbers. Who can tell me if this is what I'm looking for?

Thanks! Matt
