bad torque convertor? how to tell

[EXTREME02]

Ihave the same problem with my extreme if you find out what the problem is let me know. I have done ever thing i could think of too

[BlazinUP]

do you have a stereo system..in your truck?

if you do get a good new battery.......
and high out put alternator//////...
i found my new system was taking more from my electrical system...than it could put back fast enough...eventually damaging my batt making it weaker///
as a result my fuel pump wasnt getting enough juice to power it at high rpm's........
got new batt.....fixed.....next im gettin a high output alt.....and a capacitor......
hope this helps...........
