Hey guys, My wife and I moved an hour and a half from my home town, and on the three trips it took to move our stuff, the TC unlocked, and I'm not exaggerating, probably over 1000 times each way. I finally had enough and stopped at Tranco transmissions in Port Angeles, the guy in there had a list of all the things it could be, as in a list of 20 things related to this issue. He said that they had dozens of our trucks in over the years and the one thing that fixed 98% of the TC unlock was a simple ground wire added, t-tapped off of the ground that goes to the TPS. It was the easiest and cheapest place to start. Well let me cut to the chase, the problem is GONE!!! In the past three months of driving back and forth the hour and a half, not a single incident of the TC unlocking! Now all of that being said, about 3 weeks ago, my transmission decided to take a dump and I had to get it completely rebuilt. I'm sure the last 3 or 4000 unlocks didn't help as it was really beating the transmission up pretty hard. So $3500 later with a basically brand new transmission and an upgraded billet TC, and all new electronics, the truck is like brand new. I have owned this truck for 18 years and it has never shifted up and down like this! I even have back pressure going down hill simply by touching the gas pedal. This is crazy! Anyway, just wanted to give an update.

UPDATE!!!!!!!!!!!! Ok it's been a while since I was on here, and a lot has happened in the last couple of years, but the main reason I am here is that I fixed my tranny unlock and locking issue after 18 years!!! Back on earlier pages I posted some pictures showing AC voltage getting into the system, higher than normal. Unfortunately Photobucket kidnapped and is holding for ransom the pictures that went along with that thread. But that doesn't matter now. As I stated in my earlier posts, I had the alternator rebuilt as half of the diodes were fried. And while that seemed to help with the issue, it eventually came back with a vengeance!. That was within a few months of what I thought was the fix, at least in my case. Unfortunately, because I have been driving a work truck back and forth from my house to work (less than 2 miles) my truck has basically been unused for the most part for quite a while. Fast forward to about 2 months ago, my wife and I moved 75 miles North, and in the first three trips in the truck, and this is not an exaggeration, the transmission would unlock and lock each way, close to 1000 times. This issue obviously has got worse by 10 times what it used to be. I finally stopped into Tranco in Port Angeles on one of my trips and asked the owner if he had run into this issue with these trucks/transmission combinations. Well he said, funny you should ask, and then he showed me a sheet from all of the things that could be causing this which were about 20 different things listed, but he focused on one that they have found to be nearly 90% successful in getting rid of this problem once and for all and nobody has come back with the issue rearing its ugly head again. Backing up to about a month before I finally stopped and figured this out, I had read and thought that I would replace the TPS, which I did, and after installation and setting the voltage within specs, I calibrated the pedal and hoped to see a difference. Nope! Nothing changed. Fast forwarding back to the transmission shop visit and by the way this guy, the owner was awesome and super friendly. He walked out to my truck and looked at something and said that my truck was in line for this procedure since he could tell right away that it had not been done yet. Ok here is the fix, for me at least. The wiring harness that plugs into the TPS has like 6 wires, and one of them is a black with with a yellow tracer, which is the ground wire to the TPS. He said what they have been doing is tapping into that wire with a good soldered t connector and running a separate ground up to one of the 5/16 bolts that hold down the air intake housing. I said that I would give it a try. I drove home, 60 miles from there to my house back in Forks. The tranny unlocked and locked back in hundreds of times, probably 800 to 1000 times. Anyway when I got to town, I stopped by a shop where a guy that I have known for 30 years owns and works and told him about this "Fix", this guy is the Rainman of auto electric work, and he looked it up on the schematics and confirmed that the black wire with the yellow tracer was in fact the ground to the TPS. So he got his tools and spliced in the T to the ground and up to the bolt. I'll end the suspense, I drove back to Sequim 4 times since then and it has not unlocked one single time!!! Now that doesn't mean that this will work for everyone, otherwise the bulletin would not have 20 things listed that could be causing this, but like the transmission shop owner said, this is the easiest and cheapest thing to try and it has worked for at least 30 trucks like this over the years with no repeats. I just thought I would share, because if it helps just one person....well you know the rest.

Yeah I still have full coverage on my 99, it has 130,000 in the engine and so Iit still books close to $10,000, but at some point I should just put the diference between liability and full coverage in the bank. I just want something back if it gets stolen or totaled.

Ok so thats two for Amsoil. Hmmmm you guys didn'the take the bait. Lol
I don't want to start a war but I need to change oil. Any oil recommendations? I've been using full synthetic amsoil for the last 3 changes. But wondering if there's a better option.
Oh ok thats good to know, are they hard to hook up? You have to drill and tap a couple of things right?
The problem is the pillars on these trucks already create blind spots, thos gauges look like they make it worse. Are there othere location options?
Thanks, thats what I need to do then. Gauges....I'll do some searching on here.
