After reading a lot of positive messages about using an S2 tranny or R&P on a 951 I have decided to replace my stock 951 tranny with a S2 LSD tranny I have lying around.

I was wondering what to use for cleaning the inside of the S2 tranny.

Somewhere I have read that I should fill up the tranny with DIESEL and let the car go gently through the gears for some minutes.

Is this a smart thing to do?

Rip It

why would u want to clean it, did it get dirt inside, just drain and refill it.

Agreed, unless you know that there are problems inside, just change the fluid. And you could change the fluid again after a 1000 miles or so.

If there is a problem, it would be best to open the case up and clean it properly. I would not use diesel, or any solvent, as a replacement fluid, even if only letting the car spin the input shaft in neutral. Too many bearings in there need lube.

Ok thanks!
