Hear, hear! I fully concur. Doing the work oneself (with a qualified helper, if need be) is a great way to become intimate with your vehicle.
After several repairs and tinkers you end up knowing the ins and outs of the vehicle. This sure does relieve the worry about breaking down on the road and becoming a bewildered, panicking mess.

Great job on the install! Will we get a video of the initial trans training/hotrodding?

Your electronic and computer skills put you in a class of your own and we appreciate your sharing them here. We all seem to have our own niches. Hey...maybe between us all, collectively we can approximate a real bus technician/repair guy?

Anyone need any metal melted?

All the kudos aside, you have more than the "regular tools" when it comes to electronics. I have a OBD II scanner that can reset the codes. I can't program or data log with it. That is average to high average. And completely useless with a diesel bus.

You might not have a 15 ton lift to bench press a 40 foot bus but I'm also willing to bet you have more than average in hand tools as well. I'm not scared of a ratchet but there's a big difference between changing the oil and doing an in-frame overhaul.

That said, it's about time for me to leave and go burn some metal. Something I've learned since getting the bus.

Burning metal is a skill I havent yet gotten the real hang of.. oh Ive tacked a couple pieces of metasl together and then beat the $h1t out of it with a BIG hammer and it didnt come apart.. but real world i havent fuzed anything together yet..

here we go.. I wired up the computers! HAL9000 its not. but im told they can shift gears better than I could, so I let them have a job in my Bus..



then comes the little parts of this where you have to Read CAREFULLY and not let your eyes play tricks on you.. connecting the transmission computers to the engine computers..

first is to connect up the TCM to the accelerator pedal.. since mine is an electronic engine, its just a wire. looking at the wiring diagram, we want the wire that "wipes" across the 5 volts and the ground.. this is a variable resistor that returns a voltage back to the computer based on how far down you have the pedal. Read carefully.. it is the second wire in the Schematic diagram but it is in position A (pin 1) of the connector and it is circuit 99B.. yeaoow!.





confused yet? really why they use letters and numbers to designate circuits and then letters that are different to designate connector pins...



Next we needed to connect the speedometer output of the TCM into the engine computer.. so another lesson in read carefully.. the wire we need is the + signal for the speed sensor.. whic is circuit 47 and plugged into pin A of the connector.. circuit 47A which is plugged into pin B gets grounded out.



for those that havent worked on Navistar much.. a little trick! if you peel back the plastic tubing on the wires.. you will find that their circuit numbers are printed on the wires thenselves.. sometimes its hard to see but it is indeed there and very helpful if you are using the manual to help troubleshoot or find stuff..

I also took another stab at plugging up that port on the transmission andyet again got the wrong size. grrr.. trip # 48 to the hardware store forthcoming..

That sounds like welding to me. If I had a better visor my welding would improve 10 fold.

Looking for confirmation? If so, yes I agree.

No, not confused yet. And letter/numbers are common on vehicle drawings. At the very least Mazda drawings.

Yep, looks good.

Ditto for Blue Bird.

Wrong size what; pins? Wait, wire? Hardware store isn't going to have pins. Not H.D. type hardware stores.

Thanks

Thanks for spending the time and effort to take pictures and explain what you are doing in this project. I have read your posts in numerous threads, but in this thread you are explaining what you are trying to do and what you are doing and what kinds of problems you run into and that helps a lot of us that might be doing the same kind of project. I enjoy your posts in other project but I hope you will continue to chronicle your own projects as they come up. Keep up the good work there are a lot of us out here watching and hoping learn some new skills.
