Urgent tranny problems!!!! EDIT PROBLEM FIXED ON PG 2

Yeah I heard it pop this time. After I left go of the button I had my roommate step on the gas so I could listen to it and sure enough I got it to pop this time.

What a relief this is to get it fixed. Thanks to everyone for the help.

doesn't the TV cable control the line pressure? I am just trying to make sure that I fully understand here. I am about to have to do some work with a 700 so doing all the research that I can.

I did a quick search on Google...
The purpose of the TH700-R4 Throttle Valve (T.V.) and its mechanical linkage is to control both the shift feel and shift timing as a function of vehicle speed and load conditions. As the accelerator pedal is depressed and the throttle opens, the T.V. mechanical relays the motion to the throttle plunger in the valve body by way of the T.V. cable.
In factory installations of the TH700-R4 the geometric relationship between the T.V. cable and throttle shaft bell crank produces the required T.V. cable extension (pull) to throttle opening for the transmission to function properly.
In custom installation the correct T.V. cable mounting geometry must be accurately determined if the transmission is to function properly. It can not be overstated that for the TH700-R4, proper T.V. cable installation and adjustment are vital to proper transmission function and life.

Yes absolutly critical for that cable to be adjusted with out it the trans doesint know what to do the cable applys pressure to one side of the throttle valve and governor line pressure applys pressure to the other side of the valve when tv cable pressure exceeds gov. line pressure the trans down shifts ,when gov. line press. exceds tv pressure it up shifts and when they are equal or close it stays in the same gear.
