1999 996 C2 Tiptronic Transmission Removal.

[valley996]

I am getting ready to remove the tiptronic transmission from my 99 996. I wanted to see if someone could give me the step by step process so that I don't forget anything. I am replacing the torque converter, IMS, AOS, and RMS. I have done some work like this but not on a 911.

Will the tiptronic transmission come out of the 99 996 without removal of the engine?

When replacing the torque converter do I need any other parts, seals, special tools, etc?

What needs to be unhooked during the removal of the transmission?

I have been able to find some steps online but it was for the boxster.

Thanks to everyone.

986/987 use the same "Z.F Tiptronic" as the 99 996, so all actions, in terms of motor/Tip. removal and repair are pretty the same.

To relplace the front seals (converter snout and front pump) on a Tip, you need at least three special tools, which are the same ones used on VW & Audi.

Yes, "Z.F". make Tiptronic (MY 99 - 996) come out without removing the engine. The later on M.B. make Tiptronic not.

When installing the new torque converter do I need to replace the transmission seal that is around the main shaft that goes into the TC? or if it's not leaking and looks okay just leave it alone?

[RFM]

It is usual to replace the seal, to avoid problems as leaking, and have to do all the work over again. Have you ever replaced a torque converter? Pay special attention to the different and separate, but collinear splines, both on the shaft as in the interior of the converter, they must aligned all the way. Check and measure the height of the converter relative to the bell housing before they are separated, this is very important not to ruin the Tiptronic.

No I have never replaced a torque converter so I do appreciate any advice.
