FrankOC Posted March 18 Share Posted March 18 I just installed a bowtie stage 2 2004r and am now checking initial pressure readings. In reverse, 1st, and 2nd the pressure gauge bounces/fluctuates by 50lbs. In all other gears the pressure is steady. Transmission has 11.5 quarts of fluid, including the torque converter, per their instructions. The pressure fluctuates with and without the tv cable installed. I’ll call them Monday but was wondering if anyone here has experience with these transmissions? Thanks Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted March 18 Share Posted March 18 The tv cable is of utmost importance. It must be set and used otherwise the transmission will cook itself from lack of proper pressures. The 700r4 and 200r4 rely on the tv cable unlike a th350 or the electric "kick down" on a th400. 3 Quote Link to comment Share on other sites More sharing options...
FrankOC Posted March 18 Author Share Posted March 18 Agree on the importance of a properly installed tv cable. I have a 4lb difference between no tv and tv hooked up at idle. It’s the bouncing pressure that I’m curious about. Quote Link to comment Share on other sites More sharing options...
Scott S. Posted March 18 Share Posted March 18 Hi Frank, The t.v. cable is a finicky thing to set.... Usually requires a few road tests and a good transmission guy. Try not to drive too much in O.D.without it set correctly or it'll eat up the O.D. I'm assuming this version has a decent shift kit included. There's a chart on T.C.I.'s website that will give you min/max working pressures for all the gears. Hope that helps. As for the fluctuations, that's tied to rpm's. The lower gears will bounce because they're working harder (spinning faster) whereas in the upper gears the flow is more constant Scott.

FrankOC Posted March 18 Author Share Posted March 18 Thanks Scott, Not driving it until Bowtie support gives me the green light. They are pretty particular about their setup procedures. 3 Quote Link to comment Share on other sites More sharing options...
cbolt Posted March 19 Share Posted March 19 Did the transmission not come with instructions on how to set the TV cable initially? Mine had instructions for an initial setting to get me close enough to drive it to my local trans expert so he could set it correctly.

FrankOC Posted March 19 Author Share Posted March 19 It did, the initial tv install went fine. It’s the fluctuating pressure reading in reverse, 1, and 2 that I’m wondering about. The pressure fluctuates by 50lbs with and without the tv cable hooked up. Taking the initial readings, with and without the tv cable connected, are in their setup instructions. 2 Quote Link to comment Share on other sites More sharing options...
