2 of 11
The Reid case has a bellhousing that is 1⁄4 inch thick at its thinnest, up from about 5⁄32 inches on the stock TH400 case. Because of this additional material and other upgrades, the SH400 weighs about 10 pounds more than a stock transmission, but it is SFI safety certified for racing and can be run without the scatter shield that many sanctioning bodies require for normal TH400s.
