#1 of 1 Geo Tracker Transmission Problem by fastdaddy55 Nov 15, 2008 (8:08 am)
I have a 97 Geo Tracker that the converter only drops the rpm [locks up] when it is cold. When it warms up it stays at a higer rpm in high gear ie; 3700 rpm 70 mph cold vs 4200 rpm hot. I just bought it 2 weeks ago & it shifts fine just turns a lot of rpm. OBD2 code shows PO740 which is torque converter clutch circuit malfunction, but I can't find any wires going to the trans, just a vacuum modulaor. Any ideas???
