canderson - I use Lubegard because it actually reduces internal transmission temperatures / verified by scan tool.
It also firms up shifting - reducing slip and wear particles.
Out of the 8 cars - 2 had known issues before application.
2-3 hard shift - SF
Very very slow shift from P to D - Audi 4
Both cured within 200kms of application

Just curious - have you ever changed the trans fluid? It sounds like you have solenoids or clutch pack issues. - - Your clutch packs could be glazed and sticking/ as well as your shifting solenoids.
New fluid - will lubricate better than old worn contaminated fluid. Just a thought.

Went to the city t go to the dealer to have the truck looked at.
On the way there it would basically lockup in 4th gear and once while throw the error code P0768 just by putting it into Drive mode.
Other times it would start fine and then when swithing from 2 to 3rd it would lock up. Sometimes it behaved like it was in neutral and the engine would just rev up before engaging again.
I found out that if I put the car into manual mode then it worked fine, no lock up and the gears would switch fine.
The dealer could not look at the truck today and said that the trans expert doesnt work on weekends so I would have to leave the truck.
I couldn't do that today so I drove around the city and the truck worked fine for the most part. It only locked up a couple times.
I am going to go back next saturday with a ride to drop the truck and have them fix it for good.

So what happened is that this afternoon I took the truck to go to town and not 5km's down the road I started sensing that something was not right.
The truck felt ithad no power and when I pressed on the accelerator it actually revved up like it was on neutral (it was in drive mode).
Super weird, so I stopped on the side of the road, shut the truck off and turned it back on and noticed right away the now famous symptons of a transmission problem.
Rough shiffting going into Drive mode and no power to get the truck going and engine light on. Checked the manul shift mode and it was stuck in 4th.
Turned around back home and read the codes with an old OBDII reader and it only had this code P0768.
Had to leave to town and took the spare care.
When I got back home I was going to unplug the battery to reset the system.
Plugged in a more recente code reader and it only read the same code.
RESETED the code and started the truck and it worked fine. Went for a drive around and everything is fine.
No error codes whatesoever and shifting felt normal again.
So was it a fluke or was just a warning of whats to come?
Today temperature went up to 8degrees celsius and rained all afternoon (it cleaned pretty much all the snow) so it was very damp air.
The truck had been sitting there since monday could it be that the dampeness threw off a sensor that it gave erroneous signals? Or perhaps some wire that shortcircuited because it was wet?

Back to square one. After a few weeks of no issues tonight i got the dreaded stuck in 4th gear again.
I read the codes and it only gave the code p0768.
I will use a different reader when i get home to see if there other codes.
This is not good. Even after clearing the code and restarting the car it goes into 4th gear right away.

|canderson||Define 'worked'. You've had that many vehicles with shifting issues???|

I had the abrupt 2-3 upshift under light/moderate throttle - - I had the flash performed - this helped a little bit, but I could still noticed the harsh shift. Lubegard red eliminated the harsh shift completely/ zero - it has not come back in over +20,000kms - - - -
That is great that you think lubegard is snake oil - it has worked for me in many vehicles <8> Japanese/German/American/Korean vehicles - and was the only additive actually recommended by two OEM's in the late 90's. - as per a TSB to cure harsh shifting / 1oz per quart of trans fluid capacity.

|canderson||There may be some adaptive learning that is taking place based upon your driving habits. If battery was disconnected for a while during the 'operation', the patient will have been undergoing a relearning process from your driving ever since.|

300kms in since the repair and no issues to report. Its a good sign.
I actually find that the gear shifting is very smooth now. I dont feel the shifting except when it goes from 1st to 2nd.
The software upgrades that were done also changed the way it shifts. I am finding that the trucks holds on into 5th alot longer and once its in 6th it also keeps it longer before shifting down... Interesting stuff.
