TV (throttle valve) adjustment on a AW4*UPDATE*
« on: June 15, 2006, 09:46:26 PM »
I was wondering if anyone on here has done it or could point me to a write up somewhere on the net that explains the procedure.  I have heard it's a pretty easy process and I tried Yahoo! and Google with no luck.  Thanks in advance! :up:

IIRC.... there should be a big section on the cable near the the arm on
the throttle body
there u should see a silver tab
derpress that with a pair of pliers
then have someone depress the gas pedal all the way down and up
then let go of the button on the cable

Yeah, I know that is one method but there is another for the older model XJs which I have.  It is the same idea but there is more to it, thanks for the input though!

Man, your good (bowing in respect)!  Upon further research I do believe you are correct.  I'm at work and the Jeep is at home so I will be sure to check it as soon as I'm off.  Thanks man!

Well, I took it for a drive today and wow what a difference!  It kind of had a clunky 1 to 2 shift and it was a little funny about when and where to shift into OD.  All of that is gone and it is smooth as silk now.  Who would have thought a 30 sec. adjustment could make such a big difference.  Thanks again!

There's actually a proper way to set TV pressure on almost every automatic transmission.  It involves a pressure gauge, a test port on the transmission, and a manual that can tell you which test port to use and how much pressure it should be making per RPM and throttle input.  For longevity's sake, it is always better to err on the side of higher pressure (clunky shifts.)   A quick way that is usually more accurate than the push button and pull method is just making sure that when you are at full throttle, the cable is pulled as far out of the transmission as it will go.  In other words, make sure that when you are at max throttle, the valve inside the valve body is moved to it's maximum as well.  The push button, open throttle method doesn't always do that.  But what do I know?

its my understanding that if that procedure is necessary
there are other problems to contend to

agreed surfrider, there should be no need to adjust TV pressure, unless something has been changed...TV cable,cable bracket, engine, throttle body, or transmission, etc.  If none of that stuff has been changed, and you develop a need to adjust TV pressure, it's a sign of a bigger problem.
