Tip fluid change ? or not.

Recommended Posts

According to the maintenance schedule:


found here under the "DIY Tools" tab, suggests fluid and filter change at 96,000 miles. There is no mention of time, i.e., change every so many years.

when you do decided to change out the fluid, ask your shop to utilize SWEPCO 720 when they go back in. 100's and 100's of shops have utilized this in the tips since the transmission came out in the 993's (same transmission) and we end up with a better shifting car with less hassles.

Make absolutely sure the shop you take the car too has a PSTII or PIWIS for checking fluid temp. This is the proper way to drain and fill the tranny (it needs to be at a certain temp)

Berlyn Services are agents for Swepco in the UK.

Changing the ATF in a 986 only drains about 1/3 of the total quantity, so I think it is better to change it before 96k. When you drain it, I can guarantee it will be as black as your hat. As Brad says, it is important to be able to read the ATF temperature to get the level correct.

By the way, I don't think the 993 Tip box is the same as the 986. The 993 was 4-speed.

Richard I was thinking about measuring what comes out and replacing the same amount. I have seen some really good tips on how to do the change using digital thermometers though, should that be the way to go.

The schedule for my '99 Boxster Tip is 90K miles and I had it done at 86K. It made a noticeable difference in how the Tip shifts (much crisper) and downshifts. I watched the whole procedure and although I used to do most of my own mechanical work it is something I would never try. As has been mentioned you need the proper tools and computer to do it right because a new Tip is in the 8K range and you don't want to go there over a job that will cost you a couple of hundred dollars to have someone who knows what they are doing do it.
