Powershift Clicking / Buzzing

[studebaker-R2-4-me]

I checked out the rear mount and all appears fine. I've got about 2000 miles on the entire drive train. I purchased a HD high stall torque converter from Bob Helm and a rebuilt powershift from Don Simmons last year. I installed Dextron 3 for my choice of transmission fluid this spring when I started the whole shebang up.

I decided to change the fluid this morning to Type F with Studerich's recommendation.

The Dextron 3 fluid was a tad smelly and not as pink as I would have liked.

Last year when I purchased the Torque converter, it had a wicked smell and little fluid that was in it was quite dark when I received it from Bob Helm. I flushed it several times with Dextron 3 prior to installation. This smell was similar to the oil that I just removed from the transmission only not near as bad.

I just took the Hawk out for a quick spin. The noise is gone and actually shifts better now than before.

Hopefully I have resolved the issue and I am now under the assumption that there may have been some residual oil in the torque converter from the get go tainting the system.

I am going to check the transmission fluid after coming back from the Pure Stock Drags and see if it is still over heating the fluid.

Thanks for the info.

I would double check those mounts as StudeRich suggested -especially if you've been practicing your launches for the PSMCD's!!! I've had a couple brand new ones fail shortly after installation, causing misalignment and the buzzing/clicking tranny situation...

The buzzing is also characteristic of fluid problems, #1 is LOW, or clogged filter, wrong fluid.
None of which seem likely in any of your cars, as you seem pretty particular about them, but could I have missed any fluid related items?

You do have a good brand of Type F or a Synthetic in it right? I wouldn't think you would use any of that "Universal" crap.

Rear engine mounts properly installed, and include a 1/2" spacer on the drivers side?

The buzzing that Jon addresses is very rapid, more equal to engine speed. I would describe a 'click' as slower in frequency, more equal to driveshaft speed. You have no noise until the car is actually moving? Might want to look at the u-joints.

Well, I've been under that car 5 times tonight. Jacking it up, setting up jack stands and adjusting the pressure control rod.

I started out extending the rod's clevis two full turns- still buzzes. I Came back and retracting the clevis four turns back - still buzzes. Ok my the pressure is high enough. Back to the shop. Set it back to the starting position and extended 4 full turns. Went for a test drive. Still buzzes and shifts way too early. Ok that didn't work either. Maybe I need more pressure, retracted the clevis 8 turns. Confused yet? Went for a test drive. Now she's shifting hard into drive and still buzzes. Back to the shop. I extend the rod to reduce pressure 4 turns and back to where I started. Well that was a waste of time and have a couple of burns on my hands just to tick me off.

Haven't gone for a test drive. Going to pour a Jack instead. I not talking to Jacqueline and will deal with her in the morning!

Any clues would be a help.

I've noticed lately my powershift transmission is Clicking when taking off. Mine makes no noise in park neutral or reverse. Jon Myers describes the condition on Bob Johnstone's site:

My situation is a new engine/transmission combination, new transmission mounts etc. so I am starting from scratch.

The shift is fine, down-shift fine too. To eliminate the clicking sound do I require more or less pressure on the control valve?
