Inspection of Drive line.
Hello fellow Volvo Drivers,
My 1991 740 Turbo sedan recently had a transmission conversion done, AW-71 or the such to an M-47. I took it for a 500 mile or so test drive and every thing worked like a Volvo, as it should. yes, though i would point out that after a 200 mile drive i noticed putting into 4th gave me a bit of a grinding, 4th is the only gear with this glitch, hmm. when the trans is cool this 4th grind is not an issue.
And moving right along, I am starting to notice a sound as though the drive line/shaft is wobbling and feel the stick shifter gyrating as this sound occurs. usually this occurs either when the Volvo is cold and/or from first to third gear. putting the clutch down and slowing and driving in 2nd or 3rd, the gyration or apparant feeling occurs. I wish to inspect the drive line components to ensure all is well and/or resolve my Volvo's ailment. Please, what suggestions are there in procedure and things to look for?
I have a Chilton Volvo 1990-98 coups/sedans/wagons repair manual and a "hit-and-miss" guy i can talk to for know-how on extensive repair...nontheless, this repair manual is a bit vague at points. I also have looked at brickboard's 700-900 maintenance guides, which are quite awsome.
Any help or suggestions will be appreciated, thank you all.

RE: Inspection of Drive line.
hey thanks for replying,
ok, so i would be checking for a wobble with the bearing or unsmooth travel correct? what else can i check via on-the-spot visual ques upon a possible culprit.
So, reading guides for this, i will attempt to remove the drive shaft with alingment in mind. any snags along the way to look out for when removing the shaft? excess pressure needed? contingent supporting?
i read the m-47 has a 5th gear vertical placement issuse regarding lubrication. onwards suggesting at least two quarts of either a default of engine oil or another suggestion is ATF A/T fluid. you hear anything about this? I believe i read it on the brickboard FAQ tables.
Hey, again thank you.

Thank you,
awsome, looking at the rubber bushing for the center support bearing it was a bit mooshy, though i have no other example to compare it too. I was able to move the driveshaft around with the rubber bushing more than able to allow for the movement, with this movement i was in no supprise as to why there might be a vibration. with regards to the bushing's integrety; should it feel more firm or soft, i would say t'was a bit soft, a bit softer than tire rubber.
and n/m the tranny comment. i saw a website regarding it's resolve.
