Tranny Issues

[88Racing]

Between 10K-20K I did some car transporting but since the auto slump I haven't done any real pulling for the last 7K. But at 20K my tranny had a complete flush, drain and new fluid and filter done to it. If I am pulling a lot every 20k I do that and I do see some improvements in shifting. But with the problem I have everything goes away when put back to stock. Bill has advised me not to reflash. Your symptoms will have to be addressed by Bill I think. Yes my hex is a TEJ one but yours looks like a newer version, mine looks more 1st gen for the 06 year.

Btw what gears and what size tires?

Ah, the famous TEJ hex code again, I completely overlooked that in the original post! Since the components in the transmissions don't change (at least not much), in a model year, I wonder why there is a need for all the various "strategies"? It simply doesn't make any sense to me.

I suspect all the different calibrations are related to all the possible engine/transmission/driveline choices: 2WD/4WD, 4.6/5.4, Flex Fuel/non-Flex, 49-state/50-state. So with just those options, the matrix is 4^2, or 16 possible combinations just in one model year. Only my guess....

Dang, Sburn! You're trying to put me out of mathematician business here, aren't you? :sadface:

I wonder though, how much difference flex/non-flex fuel is, and, 49/50 state differences seem like they should be minimal too.

However, I suspect you're dead right on this!

Functionally, I suspect there’s little to no change between those two flavors. Maybe labeling is done that way to satisfy some regulatory requirement or to be able to prove something to the EPA (flex) or CARB (50-state).

I know as a Kalifornia resident, I can't go out-of-state to buy a new car and bring it back here unless it's 50-state certified on the VECI label. I imagine a 49-state label could easily come unglued and somehow a 50-state label might get put in its place, leaving the PCM calibration as the only true way to tell the 49/50-state status.

Back in the 70's-80's California cars did have some actual hardware differences that were unique to our Golden State. NOx (nitrogen oxides) valves in the distributor vacuum lines, I think it was. Maybe cats and EVAP stuff too before the rest of the country got them. I don't think there's been any actual hardware differences between CA and the other 49 states in a while now. But that's all fixing to change again when CA goes to their own CO2 standard.

Tonight I ran to the golf course and watched it closely. Had the same symptoms as soon as I took off, it would shift way too early, I was in third gear at like 30 mph and as I slowed down again it would not shift back down until I slowed to a stop and then it would finally shift down and I would feel it shudder as I came to a stop. So, now I am really concerned this deal is not going to clear up and I am going to have to fix my truck just out of warranty, just my luck. Not to mention if it was one year newer I would still be under the powertrain warranty. Anyone have anymore ideas? thanks

Could possibly be more than that by the time you take into effect all model aspects.
Like 6^4

Oh great! Now Lars is getting "combinatorial"! I might as well quit right now!

And to SBurn - do you get charged for "service" if they put air in your tires (I bet)? It's one way to help a business in this economy, I suppose. That bit about the paint is just over the top, isn't it?

I haven't heard of anybody getting charged for getting air in their tires, at least as a separate line item on a repair order. But I don't know any auto shops in the charity business, so I'm sure the shop owner covers his expenses for this State rule somewhere in the general shop rate.

We also have pay separate "disposal fees" on the used oil they drain out and on the old tires they take off. And, we pay an extra few cents per quart on the new oil and a buck or two per new tire for fund those schemes.

Got to find some way to charge for the electricity used to capture air and pressurize it!

In SD we even have the service disposal fees on tires and oil changes.
Then if you get into big tires there are DOT taxes assessed.
Thank goodness we don't have emission testing yet but on motorcycles they do perform random noise emission checks.
