I've checked for vacuum leaks and used NGK plugs. ever heard of the pump not working while heading up a hill?

Well............not a flush but a filter/fluid change.

The trans is shifting slow but i thought this just might be due the the age and mileage (240k) It does act up from time to time but yet again i figured this might be due to the age. I still have reverse, the OD and cruise control both work great. The ignition components are all tight as I've been checking and re checking everything. battery terminals are clean and tight. The timing is good and the oil is clean. Good compression in all 6 holes. I've topped it up with premium fuel and added seafoam fuel treatment (used seafoam in the trans too).

Thats great, Thanx!

I have, I've replaced every filter except for the trans filter. I've replaced the cap, rotor, plugs, wires, air filter oil & filter. It seems to run great while idling and even driving it without any major load but as soon as i go up a hill or put my foot into it, the whole truck shakes and shutters.........this is where i'm stuck, the fuel pump is working fine BUT I cant tell if its pushing the volume of fuel it needs. Being a low pressure pump it could be that or.....does this sound like a transmission thing? I might just bite the bullet and do a flush , crossing my fingers thats all it needs.

Hello all! I'm new here and although very experienced pullin' wrenches, new to my Pathy. ( '95 SE 3.0 Auto) I just bought this truck from my uncle in law for 500 bucks and I love it!! Besides the typical erratic tach, it's practically immaculate body/frame/interior wise but it's causing me some serious problems. After just replacing broken manifold studs, the whole exhaust system (including the O2 sensor, a COMPLETE engine tune up and a bottle of trans tune. It's still having a severe hesitation problem under load. As stupid as it sounds I cant tell whether its a fuel issue or auto trans issue. - Could anyone tell me what the fuel pressure is supposed to be? - I've heard these transmissions go in the worst way, I've been scared to give it a full flush/filter change as in past experiences this made the situation worse. Much appreciated!!
