Just curious if anyone has looked into this. Im always finding myself shifting for the next gear only to realize that I dont have gears left...

 

On a 6 speed top speed will come in 5th. 6th is economy only.

 

You do realise that the 6spd uses an entirely different shift linkage. Your going from a shifter rod to a shifter cable. But its all good.

 

Ok I kind of figured that might be a problem. Still that would be easy enough to convert. As opposed to mounting to the bellhousing if the bolt patter is different. What about axles?

I dont drive really fast. I just like to keep a load off my engine when driving to work. I would rather drive at 2500rpm in 6th than 3000 in 5th on the freeway.
Since my tranny seems like it may be on its way out in a year or so, it would be nice if I could throw a 6spd in instead of rebuilding the 5spd.

see5: Thats the only purpose I'd want the 6th gear for anyways.

 

To answer the initial question the answer is no. A RS6F51 (A) (V) has a completely different bolt pattern where the bellhousing mates to the trans. This box uses larger bolts then the other one. Your only bet is to just use the entire gearbox becasue the bellhousing side that mates to the engine is probably the same with the exception of maybe the starter and or clutch linkage.

Nismo is right about the shift linkage being different. The RS5F50 (A) (V) use the old striker rod setup that links the gearbox to the shifter. The RS6F51 uses a cable assmbly and to use it you would also have to use the gear shift assembly as well. But hey who wouldn't want that?

 

Cool, thats exactly what I wanted to know. Thanks!
