On the CRX, there is only zero and full lockup, and full lockup can be induced by giving the wire running from the ecu to the solenoid a constant 12V. Meaning, it will lock up when it gets warm if it is getting the 12V, but not otherwise. It's odd that it doesn't stay always locked up, but that's the case. 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...
Yes, my wife can't/won't drive a manual. I resolved to driving her old car to save on a car payment and to have 2 autos around the house so it can be driven by either party.
The next solution would be to trade the 'Teg on a different, more fuel-efficient automatic. The problem is that the car holds sentimental value from an untimely death in the family, and is a touchy subject to discuss selling it.
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.
Awesome. Expecting a 15% minimum improvement on your next tank
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!
