It has an Aisin At45 transmission I believe. Just be sure to follow the installation instructions for whatever pto you install. Muncie or Chelsea. Installation instructions are available online. Had a customer put the return line in the incorrect port in the transmission and it burned the...

Pictures would help. Did you get it going yet?

Let’s back up. All of this started happening after you replaced the batteries. I suspect either someone jumpstartes the truck by connecting the leads backwards & blew a fuse. Or there is a connection not connected. The picture of the batteries looks good however… the connection on the positive...

Can you post a picture of the battery connections?

Do you have source battery voltage on both sides of the 100a and 80a maxi fuses? This would indicate you are getting power to & through the fuses.

Beeep beeep beeep sounds like a derate from the SCR. Are there any lights on or flashing in the cluster? Sounds like loss of power to the DCU. Pay close attention to corrosion in the smaller ring terminal connections on the power side. One of these feeds 12v to the DCU (SCR computer)

DO make sure the key is off when removing fuses or it can set fault codes.

You don’t have to remove battery connections to remove fuses. Unless you are removing the high amperage fuses. Some of the large amperage fuses have constant battery power on them so you will need to be careful as some of them are held on with bolts. Anything in the cab relay/fuse center would...

Welcome. First rule of hino is check EVERY fuse. Start in the fuse relay center in the cab. Then check the fuses in the external relay box above the batteries…& there is also another external fuseable link box to the side of the air filter housing. The larger amperage fuses have a clear cover...

I sent a pm, but for the record. P204F is only telling you you have an issue with the SCR system. It is a generic code, it does not tell you anything else. There are over 50+ specific codes that relate to what the issue is. Posting any and all codes will generate a specific diagnostic repair...

I would check the pass through box at the rf corner of the firewall. It is behind the air filter housing. Peel back the passenger side floormat and see if the grey jute padding is soaking wet. If it is this in an indication that there is water getting into the pass-through box. It can come from...

Looks like the High side driver is seeing high voltage. If you have already replaced the external harness with a new on that leaves.... a faulty TCM, or an internal fault with the wiring. If you had a test TCM that would eliminate the TCM at least. Be sure to check pin drag and inspect all the...

Here is the troubleshooting guide.

It sounds like it has an active shift inhibit. Make sure the TCM fuses are good. If it is a push button shift selector can you pull the fault codes? Could be power, ground, or a can communication fault. Need more info to help further.

Remove the spin on transmission filter, install a new filter pre-filled with Dextron ATF. Drain the fluid an replace the fluid with new. I worked at a dealer for 10 years and that.s how we did it. Its not that it cant be done. But you would need a flushing machine and they are expensive. Drain...

Forget it,:sweat: I just noticed you have the 6.0 gas job. I saw "HEAD" done and assumed you meant the 4 cylinder diesel.

This thing's essentially a Isuzu NPR

Not sure if you have to remove the cab. I would just remove the rear cab mounts and jack it up enough to do my work. I never had to remove the entire cab, and i even put a radiator in the Peanutmobile that Planters drives around once. I would not overlook the radiator cap as a culprit. Make...
