can I replace my 7.xL with a 6.xL ? The 7L is a '91 with auto trans. It's blown. My other truck has the 6L with manual. (puttting in a 400 or 460 gas).
Will the trannys match?
Will the computer go haywire?
Have you looked around for a replacement 7.3 or 6.9?
I've seen them go for around $1500/2000 on ebay. About the same price that a stand alone transmission controller would cost.
What controls the 7.3 tranny now?
It will work with the 6.9 just as well.
Put the 7.3 glow plugs in the 6.9 and the wiring harness off the 7.3 on the 6.9.
You will also have to use the 7.3 fuel filter/water seperator on the 6.9.
Bolts right up.
The bell housing on the 6.9 will not fit any gas motor.
The auto on the 7.3 will bolt up to the 6.9.
