what @bloc said. The gm computer uses the ISS and VSS to ensure there is no slippage in the tranny, and as speed output if you are ditching the toyota gauges.
My fear of the DD "magnifier" is error from "upscaling" the signal. I can't remember what the electrical signal from the toyota VSS on the tcase is, 2 or 4 pulses per rev, but you're looking at 10x or 20x any error. I'm not sure that this is a real concern.
But, with the tone ring being a $35 part and someone like me being able to tear apart and put back together a tranny in a long saturday, you can probably install the tone ring w/ new clutches in 8 to 10 hours if you've never been in a tranny before, less time obviously if you have done this type of work before. For less than $150 you can have a quasi rebuilt tranny, properly do the job and you get a look inside your used transmission.
Just double checking and a dumb queation, the donor vehicle was a 4x4, correct?
