hi guys great forum i'm new here and thought i could get some reasonable suggestions on my trans problems no 1st gear or shifting from 1st to 2nd automatically seems to be stuck in 2nd when you start out very slowly trans seems to slip or shutter until it picks up momentum at 35 to 40mph you can shift manually to drive and continue accelerating no overdrive when button is pressed or will not downshift automatically but you downshift maually to second and it will drop down check engine codes show po743,po755,po760,po765 had the normal explorer idiosincrisces most of it's life but nothing ever like this.... has 112,000 miles fluid full, not burnt,nice reddish color,2000fordexplorer xls 4.0 4wd 5r55e thanxxx.. brian <!-- / message --><!-- BEGIN TEMPLATE: ad_showthread_firstpost_sig --><!-- END TEMPLATE: ad_showthread_firstpost_sig -->

OK well it sounds like you have a electrical problem with one of your sensors! i have come a crossed it on the AOD "E" transmission. but does it engine brake in the manual low gears and also does reverse work good? I've noticed that the band on the reverse drum might cause some problems but i don't think your transmission would have that problem but i might as well ask! what does your torque converter stall to? that will also help me with the diagnosis!
good questions thanxx for checking out my post yes while driving in D mode at 35mph if you drop down manually into 2nd there is engine braking the other day i spent a good while up and down my driveway going from reverse to drive and 2nd there are no issues there... also if your driving in 2nd gear about 25mph and you manually shift down into 1st the engine does not brake or trans does not shift down thannnxxxx...brian
