Hi Bob,
The 3550-TKO is a 5-speed overdrive. The TKO-600 has an optional .82 overdrive that will work very nice. Your 3550 has the .68 overdrive and has the same gear ratio as the TKO-500. Both the TKO-500 & TKO-600 are direct bolt in with a change of a driveshaft yoke and the TKO-600 will need a 26-spline clutch disc.
The 6-speed is a T-56 and has 2 overdriven gears. It comes with a SB Ford bellhousing and will require a new yoke, and shorten the driveshaft.
As a Tremec Elite distributor I stock all models of the TKO-500 & TKO-600 and the T-56. I am also a service center for retail Tremec dealers, garages and end uses.
Call me will any questions. I'm offering free shipping and you would be tax free being an out of state sale.
