Metro automatic trans mod.
Hi, new member here. I searched the archives, but didn't find mention of this trick, so I thought I would pass it along.
I am driving a 91 metro vert automatic. My commute is 80 miles, approx 1/2 of which is stop & go. The automatic's shift points are all wrong for this, it seldom sees 3rd without coaxing, and downshifts too soon.
I read on Teamswift that these can be run with the shift solenoids disconnected, and shifted manually. So, WTF, I disconnected them for a week to try it out. I discovered that I can keep it in 3rd as long as I am still rolling, start out in 2nd if stopped, and get it into 3rd at about 15-20 mph. This netted me a 4 mpg improvement.
In order to retain the option of full-automatic, I wired in a DPST dash switch to the solenoids that allows me to switch between automatic or manual shifting on demand.
I don't know if this scheme works for other transmissions, but it is the hot ticket if you are stuck (blessed?) with an automatic Metro.
