92 240 wagon transmission issue?
 

I recently aquired a 92 240 wagon which everything was fine untill a week ago when I pulled out of my driveway and put the car into drive it would go very slowly and then seem to catch something and then go properly with no issues. It will also do it in reverse.

I have check the transmission fluid levels while it's hot and after I have shifted slowly thru the gears. The level is just a bit above full.

Other than that issue the transmission shifts smooth with no issues even at dead stops it accelerates fine. It only does it after it's been put into drive or reverse from park.

As always I appercieate any help solving this issue.:)
