The Turbo 350, aka TH350, automatic transmission is a stout 3 speed
automatic transmission. It has been used in various GM cars and trucks
over the years. Because it is a reliable, common, and short
transmission, it is probably the best automatic transmission to swap
in a short Jeep such as a flat fender or CJ-5.
Swapping a TH350 into your Jeep does not make much sense unless It
is used with a GM engine. The engine adapter is not available for all
engines used in Jeep vehicles and it adds to the cost of the
conversion. An adapter of some sort will be required to bolt a TH350
to a Jeep transfer case.
Some people will argue that a TH400 is everything a TH350 is, but it
is stronger. It is a stronger transmission, but there are a couple
important advantages to the TH350. The biggest advantage of the TH350
is that is is 3" or 4" shorter than the TH400. It would be very
difficult to fit a TH400 in a pre '72 CJ and hard to do for a '72-'83
CJ-5. The couple inches makes a big difference which makes it an
excellent choice for a short Jeep. The other advantage is the TH350 is
more efficient than the TH400. The Turbo 400 wastes more power than
the Turbo 350, so the Turbo 350 will have a snappier feel.
