Mileage Gain 700R4 Automatic to NV4500 ManualMarch 20, 2014 - Author: bartbarton - No Comments
I have that 1972 Blazer, thanks for the cost estimated to convert from automatic transmission to manual 5 speed NV4500, I need more information. I understand your upgrade kit for this application includes:
- New NV4500
- New Bell Housing
- Clutch & Flywheel
- Shifter Stub Stick
- NP205 adapter.
Question: This Blazer currently has a 700R4 automatic in it that the previous owner had installed. Not a cheap conversion itself. Am I crazy even considering the 5 speed knowing it has the 700R4 in it? Will I gain any mileage out of the 5 speed?
Answer: We would expect that the NV4500 5 speed will gain 1 – 2 miles per gallon for the simple reason that the vehicle is not losing power thru the torque converter. The NV4500 is a lot stronger transmission than the 700R4 so decision is going to be based on what you do with the vehicle, if it’s a heavy duty application you probably want to proceed.
