So I bought my F150 in October of last year from a local dealership as is, no warranty. You live and you learn. Truck worked fine, except it would have this vibration all the time. I brought it to my friend who has a mechanic shop, his findings were that you could grab the shaft coming out of the transmission and move it up an down, it had so much slack. Besides that, it shifted great, temp never went above 195 according to the dash. He replaced it with a Moveras transmission, 15k miles later and no trouble, the only thing that concerns me is the transmission temp. Going 80 mph itll go to 210, then go down to 208, then 206, and 204. 70-75 mph its 203-204. Just concerns me cause the old transmission never went above 195. He did replace the trans cooler when he replaced the transmission. I've read I could upgrade to a heavy duty trans cooler, is this possible? I'm undecided whether to keep the truck or not, I recently became an insurance adjuster and I'll be traveling alot, even with the 3.7 V6 its horrible on fuel, 15-17 mpg most of the time, but it is a crew cab 2wd. I'm considering a long bed Tacoma crew cab, 2016-2020.
