83 300SD trans slipping/flairing when cold

I replaced the modulator and adjusted the pressure to factory spec about 3 months ago when I first got the car. Also at the same time I replaced most of the vac hoses and connections under the hood. The trans seemed to shift pretty good for its age, with a very small 3-4 flair.

One night after getting off the interstate 3rd gear just didn't engage. After trying to limp home for a couple minutes, I got angry I just gave it gas and all of a sudden it shifted and worked. The next day I changed the trans fluid/filter and added some Lucas. Now first thing in the morning it slips VERY bad going into 3rd and has a VERY noticeable 3-4 flair. If you floor it all gears engage solid, but it seems like it doesn't want to downshift and it seems to be shifting early too.

1984 300TD crank/no start

I just bought this car. Auto trans. Sat for 6 months. 150k miles. Just replaced battery and fuel filters. I read other posts. Glow plugs read starting from front(#1 10.7v,#2 10.8v, #3 10.9v, #410.9v, #5 11v). Loosened one injector line and fuel was coming from it.

Seems that I have fuel and power to glow plugs. Its 70 degrees out.

What is next? Comrpression test? Should I buy Physical Exam kit and then adjust valves and do a comrpession test?

Any guesses as to what problem is?
