  • pressure fitting on 66 Stude V-8 HD automatic tran

    I thought an hour would be all it would take to find, attach a guage and read out and adjust the cable on my automatic trans.
    An hour later, I gave up trying to find the fitting to remove on the left side of the trans case as pictured in the shop manual. Has anyone got an idea where this correct pressure fitting is?
    Thanks,

      Lou, Brian's '66 Sport Sedan has the HD Flight-O-Matic trans with the cable throttle control for the Chev. V-8. All of the Studebaker engine versions always had a 3/8 pipe plug, low on the left side of the front of the case near the mounting flange, as shown in the Shop Manual, but apparently it has been re-located or something, on the new case for cable control!

      It would not be the first time that the Manual used an old pic from the '64 book, and the '65-'66 case, either has no test port or it has been moved!

      I am wondering if the pressure fitting to the oil cooler on the right side forward, would have the same pressure?

        Dwain emailed me a service letter that states "The pressure port is located on the rear face of the transmission case on late 1965 and all 1966 models."
        So, I'll have to roll my creeper farther back and investigate that at first light! I'll report my findings.

          Mission accomplished! Jack car up, crawl under, attach pressure guage to fitting, start car and warm to operating temperature, pressure at hot idle, http://farm3.static.flickr.com/2041/2187546897_757f32b606_m.jpg[/img]
          Pressure at just under 1000 RPM, 90 psi. Road test after removing guage, and voila! Done deal.
          Thanks all!

            So, Brian...does that mean it now shifts like it should?

              Yes Dick, the shifts are smooth and on time. I think 2nd to high should be around 20 mph. Drove the car Saturday, the truck on Sunday
