Collect a FACTORY chassis service manual which covers the engine and drive train except for the transmission. Some of the GENUINE FACTORY service manuals are available on CD.
Collect a FACTORY Allison transmission service manual. Again try to get it on CD
REAL manuals not the pretend wanna be's, have flow charts for diagnostics and diagrams plus photos.
I am no hypocrite. I have FACTORY service manuals for the CROWN, the Cummins 855, Fuller with road-ranger aux. transmission, the SQHD axles, and finally the MoPar manual for the toad.
