Transmission problem


GlennWest

Recommended Posts

Well it let me down. Ultrashift. Going to get it inspected today and coming out of town stuck in 8th gear. Went to turn around and that was it. No downshift. Disconnected batteries and waited. Hooked back up. Now have neutral so truck can crank up. But that all. Just busses error sound. Got wrecker coming. Was working fine until this happened. Any thoughts on what to check appreciated. Towing to my property so I can work on it.

I may have a wire problem. It just quit when it done this. No shift and f flashing on display. Had to disconnect batteries to get neutral back. Now nothing but buzzer noise and neutral display when attempting to put in D.

Kk. Do that morrow. If fuse blown something causing it but that sounds very possible. I didn't know where fuses are. But I do have neutral. Display shows that too. Error noise when in drive. So I assume computer working. It on my property now.

Is it common to pull rear axle out when towed?

Yes... It's easier and safer than dropping the drive shaft. Did the tow operator cap the hubs?

Can only to speak to similar symptoms regarding the Autoshift in my 2003 vnl. Lock up in gear. Reset and go down the road a ways. Lock up again. Least expensive was the wiring harness replacement. No change. Changed the xy shifter, problem solved.  Good luck.

Mine was worked fine ever since I got it. If the xy shifter worn out I should have been getting issues. This was instant failure with no poir issues. Only issue I have ever had is it holds the first gear, second, longer than it should sometimes. Not terribly though. Also when I bought it they commented they had to replace shifter. It was thousands of dollars also. So that sounds like it is new.

Please take a moment to check voltage to the ECU of the transmission.

Be sure that 12 volts is present, and that the ground is clean and secure.

With the Volvo, the lack of good ground at the battery from the transmission computer caused a similar condition for me.

What was the last thing you had done to the truck?  Start there and work backwards.  Before disconnecting everything, try to tighten everything.

Last thing I did was new batteries. Cleaned everything up good, put star washers on connections to get good bite. That first place I went. There is a fuse in there though I didn't check.

This might be related or not. My truck now cranks right up. There idle goes to 1k rpm. Then returns to normal. Does this every time I crank it up since transmission problem. Didn't do this before.

That circuit goes to rear axle area. Don't think that is it. It goes to back of truck. Likely my battery charging wire. Fix that later. So still at zero

I was looking at some youtube videos and it seems easiest way for is remove XY shifter and just replace the sensors. I have no idea how to diagnose them. Seems they not very expensive. That service door should be right over it. Or can anyone tell how to find codes? all i have is an f on display. I just goggled this and found a ranger article and it stated all trucks you can turn key on and off 2 times and get codes. Try that tomorrow. 'Got feeling it speed sensor.

Glenn,

Mine did something similar but it showed this.  BTW if you replace sensors they have plastic bodies,  are brittle, and break easily so a 15 minute job can become 9 hours.  GeorgiaHybrid and I know from experience.  I have Ultrashift.

Do you think it would be easier just to remove XY shifter since they are connected to it. It is going to be a mirror job if i try to do in truck
