Chevy 350: I'm going to answer this one for Jake. I rebuilt my first TH350 in 1980 which went into my 64 Chevy II drag car. I bought a B&M Transmission Kit 30229 (I didn't know Jake then so I couldn't buy one of his rebuild kits which I'm going to buy one of his kits here soon to rebuild our youngest son's TH350), a B&M Manul Pack Kit 30219, and followed the directions to the letter. The transmisson is still in use in another car (the last I knew, it was in a Mazda RX7 with a 355 SBC being hit by a 250 HP NOS system!). I would have to say that anyone with a good working knowledge of hand tools (feeler gauges, wrenches, piston clamping tool, a length of 3/8" chain to pull the pump, etc.), able to follow written direction, and have clean work area should be able to rebuild an automatic transmission. You also have to inspect all the parts, case, and valve body so that you don't put badly worn or broken parts back in. Good manuals help. I have Helm manuals, Chiltons, Motors, Haynes #10360 (which is a really good automatic transmission manual), and now Jakes instructions to go by. BTW, I do NOT advise putting a manual pak kit in ESPECIALLY in a street car. It can be dangerous! Understand that with a manul pak, when you select a different gear, the transmission WILL shift into that gear! If the engine is at peak RPMS and you select a lower gear, say goodbye to your engine, transmission, axles, and possibly your vehicle! I prefer to modify the govenor so that the transmission shift points are raised to the peak rpms of the engine. Our youngest son's 83 S10 that has a 350 SBC with a TH350 shifts at 5600 rpms every time with the shifter in drive.
