Today, I had a few mins that I could have disconnected that wire and recorded voltage from it... but then it rained. Tomorrow, I'm helping a friend sort out wiring gremlins in his gas hog truck, then I have to drive about 1/2 hour to get two Honda Motorcycles I just bought.

Some day...

By the time I get around to playing with lockup, I'll be swapping for a manual anyway, it seems.

keeping it on the list...

Been too busy with the house to do any ecomodding. What started with a wax ring for the toilet gradually turned out to be replacing the floor and joists under bathroom(complete gut and renovation) and a replacement of ALL plumbing in entire house, then a replacement of well pump and tank , and driving a new well(the previous owner dropped a sand point down a 4" casing and filled it with dirt....can't pull more than about 1 gal/min).....I'm glad I am not a plumber anymore.....I'm still waiting to put in that clutch pedal...

I've been busting backside with my Son and trying to fix Wife's car... I haven't even looked at my van, other than to cut the back carpeting out. I'm probably going to get a couple sheets of Lauan and cut them to fit in the back, so I can get rid of the back plastic panels and cover the floor. I don't want the plastics back there, since it's basically a work vehicle that only gets used to haul my Family, I don't care what the interior looks like.

Vehicles are made for utility, not pretty. Wish others would learn that little piece of information...

Seeing a nice increase in my combined tanks after my TCC lockup switch mod.

26.1 mpg recent tank fill which included a highway/city run with a full load of wood.

24 mpg average 4 previous tanks. 24.6 was the highest of the 4 and that was 1/2 with TCC lock. That's +8.5 percent. Not scientific or anything but an upwards trend. Will have to wait for a couple more tanks to see if it's not an anomaly

Highway seems unchanged which is just what I expected.

Well jeez, as soon as I find the time to even pop my hood, I'll probably be able to break 30 mippigs!

Autospeed has just published an article that could provide a cheap and easy microcontroler for this sort stuff.

I seem to be on my way to a record tank. Mileage on the island here with these hills must have improved a lot. I will have to do some a-b runs to see what the change is. The two best things are being locked up in higher gears up hills and cruising locked up in OD at 60KPH/35mph.

Awesome!!!!

I didn't read the whole thread so forgive me if this was already mentioned, but are you concerned about damaging the TCC? It's not as strong as the clutch found in a manual transmission and unlocks under heavier loads simply because it wasn't designed to support them. I might try this mod for my car were it not for concern about hurting the TCC.

Also, what happens if the PCM commands a shift and the TCC is locked?

It's experimental. There is no guarantee that the TCC isn't going to get destroyed, but there was never a guarantee that gasoline engines wouldn't explode when being started, so many years ago. It's all about seeing what happens.

The way that most of us drive, I don't see any issue with it.

I was also under the impression that the TCC only unlocks under load to increase engine RPMs, effectively providing more power to the transmission. I'm fairly certain the TCC can hold at fairly close to max output, but it's not like we're accelerating at WOT all the time.

If it starts to slip, it would be an instant thing, you'd know it right now.

When the PCM says to shift, it still shifts. This, as I understand it, is why orange4boy is still manually shifting for the most part, because the PCM/TCM is commanding shifts too early, and ending up with RPMs too low as a result of the lockup.

At low throttle angles, again, the shift "shock" isn't enough (so far) to slip the TCC, that I've heard/seen.
