Speed sensor failure

I have an older unit. It never worked right. FEDEX gave me an exemption. Now I have to have it working.

 

I'm bringing it back to the place that installed it this week to look at it. The service manager is telling me it's an issue with the truck not the unit. Will see what happens.

 

I had it looked at today. I was told it's a truck problem. They offered me no solution or any information beyond that. It's very frustrating. I will have my mechanic look at it next week and see what he thinks.

 

Pretty much the same issues I have. I can not raise my idle at all. It still raises on it's own during a cold start
in the morning when it's warming up.

I spoke to my mechanics at great length today. My issues with the cruise control started roughly 10 years ago when the cruise control stopped working which was around the time I had my clutch replaced. I had no idea about the miles not recording on the ECM until 5 or 6 years ago when I had the QC installed with the electronic logs. The miles it stopped recording at roughly coincide with the installation of the clutch.

They are 90% sure it's the speed sensor on the transmission that is an issue, or the wire from the sensor to the ECM. I am bringing it in on Tuesday. Regardless of what happens here, I have decided to buy a new truck. 14 years in the same truck is a long time, the truck itself is 18 years old and I think it's just time. However, I still need my current truck for a month or so. I instructed my mechanic to keep the cost no more than $500 to fix. If it's the ECM which would be the absolute worst case scenario I am not fixing it.

 

An update on my current situation. My truck has been at my mechanic for a few days. He thinks it's a problem with the gauge cluster. When I asked how much it would be to fix he said and I quote "it's a money pit." I am going to talk to him again Tuesday and see what's going on. Truthfully I don't think he really knows what the issue is yet. I put a deposit down on a 2013 International yesterday. So one way or the other it's going to get resolved. I am glad I went with my initial instinct and started looking for a truck 2 1/2 weeks ago. I just wish I had realized a little earlier that my current truck wasn't exempt from the ELD mandate. I thought It had a 1999 model year engine.

 

It has the Max Force. I bought the warranties for the engine, Tranny, rear end and EGR/Emissions. It has low miles so hopefully, It will be ok. I heard the same horror stories about the CAT 3126. I have 628,000 miles on it and it never needed an inframe. 5 out of 6 injectors are original. HEUI pump is original. I took great care of it. My other two trucks are Ford gassers with over 200,000 miles each and are a 96' and 97' and they still run great too. You take care of them and don't abuse them they will last a long time.
