Re: Post Your 4wd Suburban Pics
Poet, The th475 is a th400 with flat cut gears instead of helical cut or angle cut gears. They only came in GMC motorhomes. I don't think they were ever factory on any 4x4 vehicle. They whine a little. The design idea is once the trans shifts, the gears ride flat against each other instead of constantly riding at an angle and pushing away from each other, creating more wear and friction. Perfect application for pulling, but not for a ''hot rod'' application. It shifts a little rough compared to a basic th400 . So externally same dimensions as th400 and it is married to my 205. I have the planatary half of a 203 bolted to the after end of the 205, making it a doubler set up so my driveline is a bit shorter than stock. It works perfect. Also, the average temp is dramatically decreased. I run a trans pow-steering radiator and brake fluid external coolers. It is a 3 speed. Thanks for the info on wheelbase length, I wasn't aware of the difference. Hey guys, keep in mind I'm not a transmission transfercase expert but I've been on a crash course since I started working on this truck about ten years ago. I'm getting there out of neccessity. But you get the basic idea, I hope. local13.out.
