pulled the buffer from the dash area. the small female connection in the pic has no plug in it. am I missing this plug? I cannot find one in the dash to plug into the buffer? Is this space supposed to be empty??? Im going to auto parts store to see if I can find a replacement. Its a Cheyenne with the 5.7 liter 350. With shifting loss. and loss of speedo only. thank you for continued support.28928a254c5a1a688ce5e939c34cec55.jpg4a12a569a93ba43be11462ab1eba0b5d.jpg

If you're losing speedometer and have erratic shifting, the most common culprit is a bad vehicle speed sensor. Is your truck 2WD or 4WD?

The P.O. had plow lights grounded using the abs ground wire. would front wheel sensor failure cause a non shift condition and no speedometer reading? My question about the speed buffer the info I have located is that the small 4 pin plug in pic is not used is that correct??

When I do a search for a replacement buffer the letters PYU are for a 95 k1500 is this a concern? I purchased a vss for a 1998 high milage Durango with RWABrakes. Does this 95 k 2500 have a speed sensor on the rear Differential as well as the transfer case ? or is there one on top of the transmission? I will replace the one on the tail of the transfer case first
Im having trouble getting the plastic buffer snapped back in place. Any. experience with placement?thank you. I see the multitude of questions your trying to weed through so please forgive my inability to work one issue at a time[emoji223]

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
