You could attempt through a switch in line with the full lockup wire and a 12v source and seeing if it will activate lockup when you're on the highway. Either that our you could neutral bomb the transmission and swap in a stick,
I like the latter idea, wait no...

From the shop manual, this isn't like the old Hondas. It actually has 2 lockup solenoids and a series of condidtions for each. The first (A) is straightforward and handles partial and half lockup based on the usual sensory inputs as interpreted by the TCU. The Second (B) handles the "Hill-Logic Control" and engages Full-Lockup when Sensor A is in agreement and enough fluid pressure is available to do so. Each run on a 5V system from the TCU.

It seems to work, but under inefficient and slightly flawed conditions. That magic number of 35-40% TPS kicks it right-in, but lift (even slowly) and it unlocks. That's the rub...

Paint me a sucka -- I don't want the batt-pack failing after a short duration.

I agree though, with gassers and especially Diesels -- mileage schmileage.

Ooooof, sorry to hear that. The politics of life. I won't make my wife drive stick, and she won't make me get an automatic, which is fair by me. We have reached transmission-d?tente.

If there is sentimental value, I would keep the 'Teg and install a stick at the best opportunity. If you bide your time, you should be able to get a manual transmission installed on your terms and at your price. That way, the only sacrifice is inter-driveability.

So Simple!!!

This was so freakin' simple I'm sick over it.

The throttle cable linkage to the transmission was loose.

It took 5 minutes to tighten.

Test Drive: TC full lockup, 55 mpg at 60 mph on the highway, at 2000 RPM instead of 40 mpg at 3000. I'm cruisin' down streets at 1400 RPM at full lockup. If I only new months ago.

It does need some tweaking: it may be too tight as the shifts are a bit harder and TC stays engaged when I let off of the gas. But it LOCKED UP TIGHT!

Boo-yeah.

BTW I'm at 1/4 tank with a 104 mile round-trip expected this week. Let's see if I can make it

Then we'll talk percentages on the next tank

Honestly -- if I knew this a year or more ago.

Thanks to Bruce for the post (and Toysrme for resurrecting it)! I looked through the Toyota manual linked in the first post, and it referenced the tightness of the throttle linkage. I thought, "what the heck" and gave it a look-see. Sure enough!

Sounds like my "tappy valves" that were actually a loose headlight adjustment screw. I'd been driving with heavy 20W50 engine oil for over a year because of that stupid screw.

Screwed by a (loose) screw.
