Need Allison 4000 Series Wall Chart To Replace HT740

[sojourner58]

I discovered that part of the Wtec III wiring harness for the transmission was accidentally thrown away last summer in preparation for an auction.  The missing harness section included the female main communications port connector, the three male 32 pin TCM connectors and the round touch pad shift module connector.  If anyone has an idea where I might locate a Wtec III harness I'd appreciate hearing from you.  Otherwise I'll have to buy the connectors separately and configure each circuit using a schematic.

I know this is a year ot two late but by chance would you still have the ," Allison HT740 core with an SAE 1 flywheel housing and flexplate adapter kit to fit 855 cubic inch Cummins engines" ? I know it's a long shot but I thought asking wouldn't hurt.... Thanks for your time.

Welcome to the forum. 

Your question is pretty specific.  I wish I had an answer for you.  If we don't get any information, I will probably move it to a separate thread and see if someone will chime in.

I believe Wayne Schell did this conversion.  Maybe he can help.

Thank you Jim. I have a Cummins 855 engine and I'm trying to mount this HT740 transmission to for my bus/camper. The problem is the transmission was mounted to the Cummins L10 originally so nothing just bolts up. I noticed on his post that he had an Allison core with all the stuff to mount up to the 855 and so I thought I would ask seeing as I have searched, and called everywhere to try and either get part numbers or the parts. And because Allison and Cummins don't support either of these anymore searching is getting me no where. He said to PM him but I'm still learning the site obviously but if anyone has any information I would be more than grateful for their knowledge and time.
