Redline 75W90NS....in the winter I could barely get into second gear until I put it in. Keep in mind that even the "good stuff" should be replaced after about 30K miles...

Steve, I say you probably have some kind of a transmission problem not oil related... How did it shift before the redline and if you replaced it with generic, how it will shift is questionable.

Well the hard shift to second only happened when it was below 20 degrees F....and got really bad when it got below zero. Then as the tranny warmed up it returned to normal. The issue disappeared when I went to Redline. My guess is the dino oil just didn't flow well when it got that cold, while the synthetic does. I've put 70 thousand miles on the car since, so I doubt I had any real mechanical problem in there...

my 944 reacts like that. It's not unusual for 2nd to be tougher - I wouldn't say it's a "hard" shift though - I think thats a little drastic for how mine was. It's not like the other gears though. I've had 2 trannys - both were like that.

Steve, I misread your post.... sorry. I thought it had a hard time shifting to second after you put redline in. I believe their claim is the additive they use gets the friction just right for the synchros where the normal synthetic is "too slick" for the synchros to work properly. I used swepco for my 85 corvette 4+3 stick tranny and I am not sure whether its a defective tranny or something else but the tranny exploded cracking the transmission case while cruising on the freeway. That was my only experience with swepco though I doubt the oil had too much to do what that catastrophe.

Well, I just put Mobil 1 75W90 in there this morning, and I'm not totally impressed. The shifts are slicker than before, but sometimes they do infact feel too slick that the synchros don't grab properly. I haven't had a bad shift yet, but it feels as if it could. The other thing is that reverse is now touchier. Well, I'll see how it does for a few weeks and some long hot trips.
Pete - if you read this, what did you have in there? Reverse was much better with whatever you put in there.
I used to use Valvoline synthetic blend in my 83 and the shifts were perfect, just going into reverse had to wait a second. Between Mobil 1 and Valvoline blend, I'm feeling like I just p**sed away twenty bucks.
