i wanted to know what some other people thought regarding this. i was having issues with the transmission shifting points etc and i've looked on forum sights around the web with the problems ive been having and they all told another person to adjust there TPS or FIPL sensor since it tells the tranny when to shift so my reading initially was
closed 0.81 wide open 3.26 that was Saturday now Sunday adjusted it to closed 1.13 wide open 3.32 i remember it said a minimum of the higher number of so i moved it to 1.70 closed... wide open 3.82 i haven't driven it after each adjustment ill have to find time soon but wanted to know what everyone thought about which one they thought was right...does it just need replacing any thought on this would be appreciated

thanks

where did you find that info? and is your trans shifting hard or to fast? i bought a new speed sensor and it corrected mt shifting pionts but now when it gets warm it shifts hard from 1st - 2nd and 3rd -4th. didnt know if your fix might help that. every shop i talk to says to replace it.

I actually have the Snap-on tool that will measure that thing, but I never mess with it. I just put it on, and rotate it back and forth till it shifts decent. Too far one way will shift at too low an RPM (hard early shifts, like firstimediesel's). Too far the other way means it revs higher before shifts. This also tends to make shifts that are a little on the firm side, and it holds gears longer. It would be great for towing.. Somewhere in the middle is where you ought to be.

If you are waaay off, the O/D light will flash on the gear lever. Also, the plug that goes on the TPS can some times be faulty, and all the adjustment in the world will not do it. I had that problem with mine. I had it adjusted to factory spec, and it would work 5 minutes and start flashing the O/D light again (with horrible shifts). I thought the bracket was bent or something, so I started fiddling with it manually. I got to a point where it seemed to be staying constant, but a little off, so that was good enough. Then a day later it went out again. I finally found that if you wiggle the wire, the light would go out. I replaced the plug with one off a junker, although I have now found a place to get new plugs from (Auto Parts Fast at RockAuto). I replaced the plug, but never got around to readjusting the sensor to factory spec. It works well enough, and at the time, I didn't have the Snap-on scope tool. Now I have it, and I'm too lazy.

i tried to adjust it more. now it sits at 1.01 closed, adjusted the max travel screw out till it got to wide open 3.85 and i just drove it to work friday and its still doing that back and forth jump when its say 32 to 37 mph range it cant decide which gear to stay in up down up down etc but its only with OD on i avoided it by just pushing the button on or off depending on what speed i was at but that was just a get me thru the day solution.

on a side note i had a bad squeal going on so i replaced the belt a month or so ago and at certain rpms it get really loud then goes away then back and 3 outa 4 times its at a certain range say 30-45 mph but sometimes it doesn't and i hear it from 24mph up to 65 others its just 30-45 i scratch my head because one time it does it next at a whole different time.i tried belt dressing and that just made it worse. someone at work said maybe bad tensioner or bad pulley does anyone know how i can check to see if its one or the other .......
