So I have had my car about 6 months now. It has 105k on the clock. No record of when the last time the transmission oil was changed. First and second gear syncros are toast, but if I am real careful I can get it to slip in without grinding. Got to put it in first just before you come to a stop. I just changed the oil (Brad Penn) and thought it would be a good time to try some SWEPCO 201 in the transmission. The oil that drained out looked pretty good. Still had an amber color to it but a little on the low side. So now with the SWEPCO 3rd has a real notchy feel to it. second will zip on the teeth as I come down from third with my usual methods. First is even more finicky than before. Outside Temp is 35-45 degree range right now. Will this get better over time? Seems like I went backwards.

I used Mobil 1 75W/90 in 944 and it was very smooth. It's readily available in your FLAPS.
Excerpt from my favorite 944 site http://www.clarks-garage.com/ "The factory service manual calls for the transmission fluid to be changed every 60,000 miles. There's always been a lot of discussion about what type of transaxle fluid to use in the 944 transaxle. The factory shop manual calls for hypoid transmission oil SAE 75 W 90 to API Class GL5 or MIL-L 2105 B, or SAE 80 to API Class GL or MIL-L 2105. What does all that mean? I don' t have a clue. Better, but more expensive alternatives to the standard transmission oil (IMHO) are Redline Synthetic MTL, Swepco 201, or Mobil 1 75W/90 gear oil. There was some discussion several years ago with regards to Mobil 1 gear oil attacking bronze synchros. However, there's never been anything to my knowledge to support that. Regardless of which of these three you choose, you'll probably notice a marked improvement in transmission shifting and noise, especially when the transaxle is cold." |
