Toyota users,
I have a very strange problem That I have been trying to solve for years.
I have a 1988 Odyssey with the 22RE engine with an Auto Trans. The rear end and been changed to a 4:56 from a 4:10. The engine starts and runs just fine and the Tranny works perfect as long as I am UNDER 3000 feet in elevation. I live at 2700 ft. so I go well over 300 feet all the time.
The problem is when I am in OVERDRIVE and go to an altitude above 4000 feet, the tranny shifts out of overdrive and no matter what you do it will not go back into overdrive until I get back under 3000 feet. Even when going down long downgrades at high speeds and your foot off the gas.
I have an altimeter in the M/H and it does its shift thing at almost exactly 3000 and 4000 feet. This was confirmed with a GPS altimeter as well.
In all other respects the M/H runs great and gets good gas mileage. I have checked all the vacuum hoses and wiring that I can and have found nothing wrong.
Any Ideas?
I also have read that a lot of owners would like to have bigger fuel tanks. Mine holds 30 gallons in two tanks. The aux tank is connected to the main tank with crossover tubes. The second tank is filled from the original during fill ups. During use, the main tank is filled from the aux tank. This eliminates the need for a large second filler tube and the need to fill the aux tank from the other side of the M/H. You will need high and low crossover tubes to allow both fuel and air to move from one tank to the other. Both tanks are located at the same height and on either side of the drive shaft, side by side. Works just fine. Gauge sending unit works for both tanks, no problem.
