Parrformance

Just finished it up today👍🏽 I’ll preface it by saying I chose to clean and dialectic all the connections at the transmission. Once I pulled a couple of connectors apart only to find pristine contact points, I decided to pull the plug out of the top port of the tail shaft. I noticed a LOT of powdered rust and debris came out with the plug. This prompted me to pull the lower plug as well. Rusty powder poured out like water, the tone ring inside however was shiny clean. I was hopeful this was the cause of the surging, but I chose to reach out to Nextran the local Volvo dealer to see if they had a new sensor in stock. Mike said we have 1, quoted $47 so I put everything back together enough to drive the truck over to get it. The cruise was somewhat better on the way over but not perfect. I took the tools I needed and had the port cleaned and prepared with anti-seize so I could slide under and install the new sensor as soon as I had it in hand. The drive home was exceptionally pleasant, the sensor corrected the surging cruise control completely, and improved the shifting of the truck. The shifts are smoother, and seem to be at the appropriate timing. With your advice Suite, I am planning on leaving the old sensor as a plug, Thanks for the advice, this made the job quick and painless.

I use synthetic winch rope on my Warn 9.5ti, would it work on the rampage?

Finally got around to changing out the worthless Stemco hub caps, I see why you like the SKF hub caps. I’m sold, thanks for the tip Jaydrvr😁

The video I referenced also stated not to bother removing the old sensor. 👍🏽Thanks Suite👍🏽

I have an additional symptom to narrow down the offending circuit. While searching the World Interwide Webasphere for a moving picture pertaining to the Eaton Fuller 10 speed with Ultrashift II, my memory got jogged to a couple of instances of abnormal shifts. While traveling home last trip, after exiting the Interstate system from a prolonged steady 65 mph travel, the transmission remained in a gear longer than usual. This occurred on an up shift as well as a down shift. The video was referring to a couple of sensors on top of the tranny, one ☝️ bout speed, front right side of the x y shifter, and I think one rear left of shifter assembly. I will check and clean all these sensors as soon as I can, hopefully by Saturday, and report back.👍🏽

Good tips, ddm502001: the truck has the Volvo 12.1, and does have the fast idle I can set with the stalk. I will fire it up this weekend and see if it will hold a fast idle in neutral. Great way to isolate the speed sensor from the ECM Crank speed sensor👍🏽 The truck CC has worked flawlessly since I bought it, this is a new issue. I am suspecting a dirty or corroded speed sensor that is intermittently giving good signal then dropping out. Feels as though the truck thinks it is going up hill then downhill in just a few seconds. If you can stand it, it will actually maintain the relative set speed albeit surging up and down. Truck runs fine and smooth with the foot throttle. Wrknrvr, I do plan to swap the sensor with new (from the dealer if available)as soon as I isolate it👍🏽

I am suspecting a dirty/failing speed sensor cussing surging while using CC. Perhaps someone else has experienced this and might have some tips? In my mind I am thinking of checking and cleaning the sensors around the tail shaft of the Eaton ten speed with Autoshift. Thank you, Michael

I can’t read 5 pages of posts just now, has the starter been removed and bench tested yet?

Yes

Yes, almost all the sites are pull through and large enough for the truck and trailer and two Jeeps with room leftover.

I agree with Rick, several grounds come together at one stud near the starter on the Volvo engine.

I had an issue a while back where the power lead to the Transmission controller, the TCM, had gotten crusty at the inline fuse near the batteries. The truck would crank but not start, because the ECM, did not receive the signal from the TCM that all was well with the transmission, the transmission did show a red blinking fault light on the control panel on the drivers seat. This was intermittent at first, but did become more frequent. I replaced the fuses holder and methodically chased and cleaned every ground.

I think I would also disconnect the battery leads for 10 minutes, then reconnect and double check transmission panel, if it’s an automatic.

I did a google search for a ptc bulkhead threaded fitting DOT, and found a few similar fittings. I am struggling to figure out how to share what I found as I am new to Apple iphone. Amazon has a version available for less than$10 Parker Hannifin 207ACBH-8 Brass Air Brake-AB Anchor Coupling Fitting, 1/2" Female Thread Sorry,$20

In between the driver and passenger seat there’s 30.6 inches of space that allows enough room for the driver to get through and access the sleeper area. As for the sleeper, the mattress area is 42 inches deep and 79 inches wide. It offers enough space for the driver to sleep comfortably. Found this with a quick search, the factory cushions take up this space, so twin sheets are likely the most appropriate size.

I replaced the entire pass through, fixed several leaks. Was not a difficult job on the Volvo.

I have had an engine run cold, never warm up, because I had a Shop do the pump. When I pulled the thermostat out there was a glob of silicone caught in the thermostat keeping it open.

Spotted a Blue one too.

Great to see another HDT, we saw this truck on I-40 between Asheville and Candler NC. Anybody recognize it.

Likely not relevant, as I own a 2006 780. I found my dash ac switch assembly to be the problem. I can switch the fan knob through each step, and hear the week sounding fan change speed. I can also move the knob slowly BETWEEN each speed setting, and stop when the fan is going full beans. I stop BETWEEN the notches. I know I could order a new switch assembly, but I am a cheap b@$+ฯ@ГΩ. I can always find the sweet spot in between by fiddling with the knob.

Best of luck, we look forward to hearing it was easy👍

Thank you Stan
