Installing a TH-700R4 transmission into a vehicle that already
has a TH-350 or Aluminum Powerglide is normally very simple
because the Th-7004R is only slightly over 3" longer
than either the short tail housing Th-350 or the long tail
housing aluminum PowerGlide and is the same length as a
long tail housing Th-350. The drive shaft slip yoke uses
the same 27 spline count so it will only require shortening
the drive shaft tube! The Th-400 transmissions used a 32
spline yoke on the transmission end of the drive-shaft so
it would need to be changed to the 27 spline unit. The drive
shaft tube would also need to be shortened and the whole
assembly balanced. You need to call your local drive shaft
service company for their specific charges to perform these
services. Our installation guidelines, included with every
transmission we ship, clearly illustrates how to measure
so your local drive shaft service company can alter it properly.
Most conversions will require the cross member to be modified
and relocated slightly or you can simply purchase one of
our custom made units.
Most original transmission cooling line sets will work just
fine once they have been "reshaped" slightly to
line up with the fittings at the transmission end.
