Tiptronic, clutch and IMS
May be an stupid question but I have to ask:
Do tiptronics have a clutch of some kind, and if they do have it, is there an usual mileage for them before changes?
IMS failure is evenly spread among both manuals and tiptronics or its impact is less on tiptronics?
And finally, how much more complex is to gain acces into RMS seal and IMS, for updating, in a tiptronic?
Thank you so much

Tips do not have clutches, they are true automatic transmissions.

Tips have a torque converter not a clutch.
Don't think there is a big difference with IMS failure/replacement between manuals and tips. The failure is in the bearing on the IMS which is not affected by the type of trans. There has been some speculation that RMS failure is more common with manuals, but no real data to back this up.
Tips have a few more lines, etc. that have to be disconnected to drop the trans. Once it is out taking off the torque converter is about the same as taking off the clutch and flywheel. They have to come off to access the RMS and the IMS.

These bands should last the life of the Tip/car provided the fluid's kept "fresh" and clean and at the proper level.
My second hand info is that the IMS failure is less common -- but not unknown -- in Tip equipped vehicles vs. manual equipped cars.
The effort to gain access to the RMS/IMS area for a Tip vs. a manual car is close to the same, close enough I don't think, haven't heard anyway, of any difference in labor costs.

The reason I found out is when I was shopping around ran across one that needed a replacement and kept getting repair quotes all over the board and finally had a mechanic ask "is it a tip or manual?" Then the light turned on, the sea parted, etc etc

All times are warranty. Multiply by 1.5 to get a customer pay $ amount.
996 Manual gearbox r&r = 3.50 TU (5.25 Customer Pay)
996 up to 2001 tiptronic r&r = 6.50 TU (9.75 Customer Pay)
996 2002 and up tiptronic r&r(engine must come out too) = 9.10 TU (13.70 CP)
So yes..... big difference in labor costs to do RMS and IMS on Manual vs Tip.

Plus you can't over rev a Tip per say. You can get type 1's but the missed shifts - say 4th to 2nd you can't have although I don't know if over rev's can or do lead to IMS issues - but it can't help...

partially correct , mk2 tips (722.6 / W5A) have clutch packs and brake bands
Tips don't have clutches, per se. They have brake bands that are activated around a drum that locks a portion of the planetary gear set to select a gear ratio. There is some slippage as the band is tightened and before it firmly grasps/grips the drum.
These bands should last the life of the Tip/car provided the fluid's kept "fresh" and clean and at the proper level.
My second hand info is that the IMS failure is less common -- but not unknown -- in Tip equipped vehicles vs. manual equipped cars.
