TRANNY PROBLEM....HELP!!

[99pstroker]

I was driving my truck running 30mph thru town and all of a sudden it acted like it went into neutral....lost all gears put it in reverse, drive, 2nd, and 1st and it wouldnt move at all. Let it sit for a minute and it moved and drove around the block and acted up again. Let the truck sit for 20 minutes started it back up and it drove about a mile and it quit moving again. Let it sit for about 45 min and i had to shut it off and let it sit 3 times while loading it on a gooseneck to get it home......any ideas?

stupid question but did u check your tranny level. If the level is ok get it flushed sometimes it makes a huge difference. Next, have someone pull codes just cause the light isnt on doesnt mean there is no codes.

tranny fluid level is good and the fluid doesnt smell like its been hot

[99pstroker]

the fluid was also flushed 15k ago

its got to be something in the sensor system...sensors do weird things wen they are at different temps wen they are bad. check the codes next chance u get.

ok....ill get a scanner put on it and see if anything shows up...thanks

first sensor id say would be bad is tranny temp sensor...if it shows that the oil is cold it will lower pressure because the oil is so much thicker it wont put pressure to it wen its hot and the tranny doesnt have enough pressure to push the clutches. I had the opposite happen with mine it was reading to high of temp so it boosted the pressure and it shifted like a standard....it was bad. just a few options, not saying im right but its a starting point

johnstula, fyi, this statement is incorrect. The other statement is correcct.
99, allmost always when you have the descreption you just gave, it's the filter stopping up. Unfortunantly, it's caused by fine metal or clutch material. If I had an emergency situation, I'd change the filter and fluid but that is only going to give you limited time and miles.
