i switched to pennzoil syncromesh fluid a couple of months ago, ive had some difficulties with 2nd and figured if it finishes it off, so be it and i'll upgrade with a M5OD-HD (or R2, whatever the newest one behind the ohc 4.0 is called) so far no troubles after 2,000 miles. and my 2nd gear problem isnt quite as bad as it was (still doesnt llike to go "in" on occasion) as far as the cold, i always let the motor run for about 5-10 min before i leave to spin the gears around before i head out. 3 qts will do it, i always get 4, put it in a clean 1 gallon containor, use a boat primer bulb with 3/8" fuel line to 'pump' it into the trans, save the extra in case i need to top-off the trans when i change engine oil.
