I'm sure I am beating a very dead horse at this point but my trans is nearing the end of it's life and I am looking for some advice on what works and what doesn't. My truck is a 90 2WD single cab dually. As much as I would love to do a swap to a 47rh or swap in a manual, due to time, workspace and money considerations, that isn't going to happen this time around. The engine is mostly stock at this point aside from exhaust and some mild tweaking to the pump but I plan on bumping up the power later on so I want to build the trans with enough strength to allow for that. The truck is used as a daily driver most of the time and sees occasional towing but not much and so far, nothing heavier than a single car trailer. Once I have worked on the power side of the equation, I want to take it up the drag strip and play around with it.
Here is my rough plan thus far:
- rebuild the original 727
- lower stall torque converter, perhaps around 1300rpm
- upgraded flex plate
- a shift kit, something along the lines of what some might call a "towing" level kit or "stage 2" kit.
I have been toying with the idea of installing a GearVendors unit on it but I have heard mixed reviews on how well they handle power and how long they last versus what they cost. Any input from you guys would be greatly appreciated. I'm a heavy diesel mechanic by trade so I have a good understanding of how it all works, I'm just not familiar with these tranny's. Thanks again!
