Transmission weird build up

[serdar255]

How is going guys? I am in the process of swapping in a G260 5 speed into my car and was cleaning my transmission, i noticed there was this funky build up that i couldnt remove. If anyone could give me some insight on how to remove it id really appreciate it. I want the transmission to be as good a possible, preferably like this.



Here is what im dealing with!

I not sure what that is, but I know that bead blasting is the only practical way of removing it.

bead blasting would be the best and easier way. another option would be a wire brush and a wire wheel on a drill. That trans you posted looks to have been painted.

It's a old ass Trans and the important part is INTERNAL; I doubt the op actually understands how to service a transmission internally; nobody on r3v does besides the guys working at gearbox shops.

For external just shove into your car; the bmw dealer can't tell if the transmission is not shiny externally; a externally clean g260 will still leak and shift crappy
