Trimatic overdrive unit

[ben]

Looks like all gm autos have hidden secrets, because with the t700 from vn to vp on top of the four gears the auto has as standard there is a plug on the auto that can be connected not sure how but you activate it on the free way or hyway and it gives you a over drive lock in gear. Going to be mucking around with that soon because if it's true should keep the revs nice and low on the free way

hey jason yes thats right.. its called lock up torque converter. i have one setup on my red van. the revs go a bit low for my 307 in it thou so i dont use it very oftern but the tranz fluid doesnt get ho which is the best thing:)
