Cat 143 H Trans no 1-4 in F or R

Cmark said: If you're replacing a coil, I recommend you replace them all. They're not expensive and when they fail, they can sometimes take out the transmission ECM. Click to expand... And if you do that you should remember that the coils are not all the same Part Number. There are 5 x 301-3118 and 3 x 323-9531.

I'll suggest that to them but its the state of PA so I am not shore how far that will go thank you

Piut it to them this way. 8 solenoids - somewhere around $200. Replacement time maybe a couple of hours tops. A replacement transmission ECM if it gets fried due to a bad $30 soilenoid - $2,750 exchange or $3,650 new. Plus the dealer service call labour to do the software install on the (blank) replacement - total spend say $5,000 in round numbers. As Clint Eastwood would say "D'ya feel lucky punk.?"

Yep yep I understand but its hard to say what the people in charge will say haha there's 3 or 4 poisons above me who make the decisions I will do everything I can to get them but its on them as to if it happens

Alright I want to say thank you to everyone for the help we ended up buying all the coils for it and I got them put on yesterday and it fixed the problem when I get to the high rang coil it was stuck on the shaft and I just touched the wires and they broke off but the bosses ended up letting us get all of them so there all new on it aging thank you for all the help and have a great day

Always nice to hear a success story. Too few peoiple ever come back and update how repairs went. Have a good weekend and happy grading.....!!

Hello everyone I am back with another problem with this grader. It just started dropping 2nd gear in forward and reverse when the grader is under load it will shift into 2nd and go down the road till you put under a load. Any help would be apprehended

As a first step check the colour/smell of the oil and pull the suction screen to check for particles.

It has fresh oil and new filter but I will check it tomorrow. I will have to find the suction screen tomorrow. When I pulled the filter out of the can there was a git of glitter in the bottom.

Regarding the screen(s) I can’t guarantee that this attachment is 100% the same as your machine but I think it is. Take photos of whatever you find in the screens. L The glitter is not good news.

I got the screen out and there was nothing in it wiped the magnets off and there was just a light amount of stuff on it. I went back to the clutch valve body and took a close look at all the coils. Coil E had the wires that looked to have a bit of heat and mice damage we replaced it and took care of the problem. Thanks for the help it really helped

The lack of particles straight away removes the possibility of a burned up clutch, directing you to the electrical/control system where you found the problem. Diagnostics 101.
