Hey hutch,
i have a question about a th-350 pump cover. I had talked to you about my trans breaking pump gears about 2 months ago. Well i finally got some time to work on it.. I switched to a .840 wide pump gear. and i also installed a different pump body. I noticed that the passages do no line up correct with the new pump cover. I took it all apart and investagated and it looks like the casting passages are off about .062 from the hole locations. All the mounting holes and the piston spring retainer holes line up but they are off with the passages... have you ran across this before????

I am going to set the cover up un my mill and run a ball endmill in the passages to make them line up. Is that a good fix????
