Hesitation in top gear
 

Hi All,

My 01 4.4 has a strange hesitation/surge, almost like a misfire when going up hills in top gear with torque converter locked up (not steep enough to kick down). Feels like some valving issue in transmission.
Has anybody encounted this behavior before??

Thanks

i have a 4.6, and i feelo l;ike when on hwy or mounhtain hills, over 100km. like theres a hesitation..i dont know if its justv the ride w/sporyt susp. on 20's or a hesitation.....i think i'm going to go 2 dealer..buit i think the engine light would come on if trouble, as i know they have good systems in it... :dunno:

I recall the 4.6's having issues with the tq converter. Check with the dealer.
