Slacker_Sam. 558 Report post Posted October 1, 2018 So I've got a MS112 Jap import Crown. 5M-E with A43D Auto trans. The bloody thing will not engage Overdrive and I cant fathom why. - I've replaced the engine temp sensor. No Joy - Tested the O/D switch on the dash. Works fine. - Traced the wires down to the O/D solenoid and probed whist operating the switch - Power is switching. - Swapped the O/D solenoid - Still doesn't engage O/D - Theres another cylinder shaped thing next to the O/D solenoid with a single pink wire going to it? some sort of pressure sensor? Basically Im stumped. Any suggestions would be greatly appreciated. Share this post Link to post Share on other sites

Hot Dog Flavoured Water 18,013 Report post Posted October 1, 2018 Will have a look at a few of the manuals I have, but Sometimes I have found that the port where the Overdrive solenoid goes is rather small, and can get blocked. I dont think I ever figured out what the Pink wire does with these lol. I think something to do with Torque converter lock up but I can confirm. 1 Share this post Link to post Share on other sites
