Update:
Well I have good news and bad. First the good; I replaced the rear trans mount, trans filter and cork gasket, replaced the flex disk, Changed the fluid and put it all back together. She is shifting again thru all gears na I am very happy to report that the brutal clunking I was getting while slowing down and a stop sign or light is completely gone. 100% better. This was most certainly the result of the seized trans to solenoid linkage that would not allow the linkage to shift back to low pressure during downshift.
The bad news is I am still having a rough and late upshift from 2to3, (but a remarkably smooth upshift from 3to4). I have spent several hours trying to adjust the modulator linkage arm, shorter, longer but no cure. Shortening gave me very erratic and harsh shifting. Lengthening gave me a little improvement in the 2to3 upshift, less clunky but still shifting too late and it made the 3to4 upshift too early.
So, next I tried to adjust the modulator itself. I turned it two full turns in (CCW), trying to decrease the pressure. The first test drive was very good. Earlier shift at 25kph and much less harsh, 3to4 shift was also appropriate at about 40kph. I thought I had succeeded however as things warmed up and I drove about 7 miles, the 2to3 shift got much harsher and clunky and later again. Ugh. Does that make any sense? that the shifting (pressures) would change as the temperature got warmer. I guess it would. So I spent the afternoon with trial and error, turned it in, out...nothing productive.
Very frustrated. I guess I will need to take a more scientific approach. Can anyone provide a source to get the appropriate M8 Banjo bolt and banjo fitting to attach a gauge and measure pressures. I suppose this is the best way to get closer.
Well at least the downshift clunking is gone! (felt like I was getting hit from behind everytime I slowed down)
Slow progress....
Any and all suggestions would be appreciated!
thanks

happy fathers day to all the fathers out there!
