I have a 94 150 with A4OD transmission. I believe that I may be experiencing toque converter shutter. Could this cause poor gas mileage? The truck seems to shutter while trying to maintain a constant speed. The shutter seems to disappear when I slow down or accelerate but is quite noticible when attempting to maintain a constant speed. Also, it shifts into overdrive when at low speeds. I have changed the fluid but have never done a complete flush. Any ideas?

 

did you drain the torqe converter? I drained my tranny, converter, cooler 20,000 miles ago and replaced with mobil 1 and i got rid of my shudder, i allso installed a transgo shift kit.

 

I've heard some good things about the Transgo shift kits. How do you like it?

 

sorry i missed this I at the national motocross race for a allmost a week, i turn wrenches on mxbikes. so far i love my transgo shiftkit. i have it the stage one setting as i am going to be getting a chip and i don't want to have to much of a good thing. nice fast and firm shifts.
