Mk7 gearbox

[Needs1975]

Hi all,

I need to replace the gearbox on my mk7.

What is the difference between 4C1R7003BA and 4C1R7003BB? My van currently has a BB?

Its a 2006 2.4RWD 6speed tipper

Many thanks

I think this is down to different gear ratios

I think I will replace my gearbox (better for my wallet I think) and not repair and I had the same question^^ I have MK7 300M Series FWD 2.2 5speed 6C1R7002DC. Thanks. Is it Axle Ratio ? my Axle Ratio is 4.23

Not sure if this is the same with Fords but with a Jaguar the last two letters normally denote an age of when a part is superceded, so BB may be from , say , 2007 and BC might be from 2008, I know when i have searched certain used parts that is what I was told by my Jaguar dealer
