The Trans-go instructions make it seem the kit is a bunch of work to install, and it is more involved than some of the slam-bang kits out there but in reality it's not that much work. Reading through the instructions before you start is always a good idea.
Don't know if I mentioned it earlier but a front pump bushing from a GM 350 turbo is the same diameter as a 727 but 1/8" wider. I always use them to better support the converter. Make sure to use a babbit type bushing, not bronze. A bronze bushing will wear out the converter snout much quicker.
Jeff, also make sure to install a good aftermarket rear servo as the pressure increase with the TF-2 kit can crack an old stock servo.
Another tip is DO NOT use a 5.0 kickdown lever as some recommend. I have found they generally cause 2-3 shift overlap. I only use a 3.8 or 4.2 lever with a stock VB even if it has a shift improver kit. The 5.0 lever was originally designed for the Hemi trans which used a wider and tougher front band to compress so it needed the 5.0 lever. Most aftermarket manual shift valve bodies recommend it and that's fine because their programmed to use it.
