more problems with this thing
ok i have a 95 f250 and im having a few problems here lately and dont know where to start with it. truck has 158xxx miles on it and has the automatic tranny. problems are as follows
1. hard shifting from first to second and second to third. vss maybe? tranny was replaced like 20k ago
2. when just driving off from a red light truck will act normal and drive but then will like lose power and rpms will drop maybe 200 or more then it comes back and like picks up speed fast like i was giving it more pedal then i am but its not the tranny doing it just like the motor goes down all of a sudden.
3. shifting is weird hard to explain sometimes its good and then sometimes it hits hard like said before but will be higher rpms before it finally shifts to next gear( like 2500 rpm) and also it sometimes acts like it doesnt know what gear to go into and almost bounces between the two gears.
all it has on it is straight pipe and intake at the moment and all the fluids and filters were just changed not to long ago maybe 1500 miles ago.
really just looking for anything you guys recommend to do to help it out ive searched and just dont know where to start with it all.

The VSS would be a good place to start. Pull it off and give it a look. You might take a look at the connector to the transmission range sensor and the sensor itself. If nothing else to eliminate that possibility.

just looked at vss had some stuff on it but i cleaned it off and all looked good checked wires to on it. ill have to check the range sensor next and see if thats the cause. checked icp a few mins ago unplugged it and it kept running good after it was unplugged also started it unplugged and started right up only started to die when i plugged it back in after truck was running without it. does that mean anything?

If diesel, sounds like a CPS problem to me.

Put a new one in, lol!
You can check the wires going to the CPS and see if the connection or the wires are corroded, but usually if it's the CPS.... you just need to change it.
I have the gray one now, but I am planning on getting the International Black one. The grey one makes the #3 and #8 cylinders look weak on the CCT on my truck.... kinda annoying.
