The trans on my pickup has been leaking, it leaked about a 6in diameter pool in a month while I was away.
I decided to look at it, it was coming from the back of the cluster gear shafts I did an oil change to the 600 wt oil, the trans was way quieter ,but still leaked.
So today I pulled it out and stripped it down.
I find there is a .006 gap between the shaft and housing, the shaft is .750 but the housing is .006 larger.
My fix tomorrow is to clock the housing up on the mill, bore it out .080 oversize, then turn up a sleave and press it in ,then bore that to the shaft size.
Will post some pics tomorrow on the job
