Re: tranny question??
They are interchangable. Syclone's use 1LHM, 92 Ty's 2LHM, & 93 Ty's 3LHM. Their are subtle difference, most of them being the evoution of the 700R4/4L60 Design. Syclone have the stiffest shifts, 93 Ty probably have the most refined 4L60. I don't think anyone would swap in a 93 for 91 transmission just for the subtle differences.
