I have a transmission problem 3rd gear seemed to be slipping it would start to go into 3rd and then it just started revving high but 1 and 2 work ok i had pulled over and was checking the fluid i pulled the dipstick out and transmission fluid just shot out of the tube with alot of force any ideas??

well first off, it sounds like the 3-4 clutches have failed (common problem) and that the vent at the top of the case is plugged...
of course as with anything, the info u have given is limited, and that may not be the case, so anything u can offer would be helpfull on a proper diagnosis.

it did this back in june it spit the transmission fluid out and i put more in there and it did fine after that until now and that was about 8k miles ago.
what might u recomend i try doing first?? Also could there be something keeping the fluid from entering the torque converter?? Thanks for the help

as long as the pump is working the conveter should get fluid. if its not getting 3rd or 4th, more than likely its going to be time for a rebuild. like i said, its a common problem with that trans..
u still havent mentioned any more details about the truck, i.e. fluid condition, how low it is/was from venting, maybe when it was last maintained, and if possible what if anything was in the pan.
lastly, how many miles does the truck have? has the trans been built b4? if so, how many miles since the rebuild?
is it a 4 x 4? if so do u go 4 wheeling a lot? have u gotten the truck deep enough in mudd to possibly be the culprit of the vent being clogged?
this is the kind of info that is needed to help try and figure out what the problem may be and the cause there of...

it has 159000 miles on it, had a new trans put in at 50k and the fluid was really burnt hadnt been changed as often as it should have it is a 4x4 and i take it to the woods every weekend when i go hunting but dont go 4wheeln the truck has been well maintained except trans fluid changes mud is a very possible culprit for the vent being clogged the trans is 6k miles out of warranty and thats a pain i really want to try everything that i can before pullin out the transmission

well, from here i say drop the pan and see if its loaded with debris. the 3-4 clutches are critical on clearance and too much will wipe them out, and plus the fact if the t.v.cable wasnt set correctly will also cause premature failure as well. i buy the alto reds for my 700r4 and set the clearance to the range they specify, (around .020- .040) i have a 700r4 in my 76 ventura that has been in it since 1996 and still going strong. it wasnt cheap, but i didnt have the money to go over it again, so i went through the effort of doing everything possible to make sure it lived. and having a turbo 350 with a 4 barreled inline 6, the gas mileage was terrible. so to me, it was money well spent. car gets 18+ miles to the gallon with no torque converter lockup. (done on purpose, i didnt want to mess with that.) gl

tnsmith10, no TV cable on this one, should be a 4L60E. I think you're right about the 3-4 clutches they're probably toast.

[tnsmith10]

ur absolutely right forgot what year it was... thx for the heads up.

with the 4L60 line of transmittins..... 700r4 , 4L60 , 4l60E , 4L65E ..

I sugggest when the filter is replaced, break open the filter for a look see inside the filter material.

A photo posted of an opened 4L60 filter... lots of debris inside.
