Hi Ya folks,
I have a 2005 , fx4, 110K miles on it. the truck has actually been very good to me, had it since 60K miles. One day after a trip to the mountains it started acting funny, going from 1st gear to 2nd it is hesitant, in higher rpms no problem at all. it will shut off when trying to park an put reverse. I have read that the torque converter might be going south. so far here's what I have replaced:
1. spark plugs
2. fuel filter
3.air filter
4. fuel pump
5.throttle body

I GET NO CODES

I read that a vacuum leak could cause it, but cant seem to find one, I have yet to access the fuel vacuum line, that sits in the back of the engine, heard it;s pretty common, but a PITA to get to.

thanks !!!

Well have you ever serviced your transmission? New fluid and filter? A trip to the mountains surely means the trans temps got hotter than normal. "1st gear to 2nd is hesitant", there's your sign (In the voice of Jeff Foxworthy).

Thank you Summers22, NO I haven't done anything to the transmission, I wanted to rule out anything else before that, on that list I forgot to mention that the coil packs are also new. Any other tests I could run?
