Autoshift conversion

I'm converting my 18 speed autoshift transmission to manual. Iv done a lot of reading and it sounds like Pablo-ua on here has done this before however I can't message him because I'm new. I believe I read the shift tower wouldn't bolt on without an adapter does anyone know anything about that also since I can't put a slave valve on it I want to keep the electric over air range valves and wire it through the neutral switch so it can't shift high to low in gear. Any suggestions on how to wire that? I know some of the gears in the transmiission aren't the same as a manual so it may not shift as good but since it's never ground a gear in its life I figure it can afford to grind a few times till I can afford something better.

 

It's in a quad axle dump truck so I don't get good mileage I get 4 or 5 depending on the weight I'm hauling. Iv had enough trouble with the transmission I'm giving up on it. It won't interface with a code reader but according to the Eaton troubleshooting guide it needs a new sytstem manager ecu which is 1800 and I'm not even sure it will fix it.

 

Hi thanks for all the info. The inland truck parts guy here told me the shift plate has a place for the neutral switch but I won't be verifying it till Saturday if not ill put a new top on it. The only shifter I found that is factory electric is a meritor and it's not an 18 so I may use it and add a switch or just make my own. I would really appreciate any wiring help you could give me. Iv also seen shifters with cruise on them but I'm not sure if those buttons are just momentary so I would have to have one to ohm it.

 

I forgot to mention its in a 2000 w9 with gen1 autoshift so it does have a clutch pedal

 

The manual stick bolted right in where th e x/y shifter was and it has a place for the neutral switch so now I'm working on wiring the high low solenoid through the neutral switch. Any suggestions would be appreciated. Does anyone know of an existing electric slave valve. Also my transmission has a plug in the area the normal slave valve would be does anyone know what that plug is for?
