When changing a clutch, what else to replace?

[geetus]

I am doing the clutch in my 96 TD Golf soon and I am wondering what else to replace while I got the trans out. The car shifts fine but is just slipping in the higher gears. There seems to be no other problems/odd noises besides that.
Cheers, Ryan.

Since the parts are cheap and easily replaced when the tranny is on the bench, I'd recommend you replace:

- both drive flange seals.  Inspect the flanges themselves for grooving or you'll be doing it again about 50 klicks down the road.. ask me how I know  :cry:
- input shaft seal
- pushrod bushing
- pushrod seal
- pushrod, if it shows signs of wear
- throwout bearing
- 2.0l of Redline MTL or GM Synchromesh tranny fluid

Did you notice a differance when using this oil instead of reg 80-90W?

what happends when your drive flange oil seals go?


Just wondering, oil everywhere spinning at the rate of the drive shaft perhaps?

Upgrade to the 16v pressure plate. Have some weight turned off the flywheel while it is off.

I'll know this winter for sure... nothing like -35C to test your syncros ;-)

Side-by-side they are very different fluids, even at about -5C which is what my garage runs without the heater.  

The dyno tranny fluid is thick... corn syrup or thicker, and is gummy on your fingers.  No doubt it lubes just fine.

The synthetic stuff is much much thinner... more like Aunt Jemima syrup that's been sitting at room temp during Sunday brunch.... and is slippery but not gummy on your fingers.

Like I said, the real test will be this winter.  The tranny I just put it in has no syncro issues currently so it's not like something will magically be fixed...but the 020s certainly get stiff during the winter months.

Then there's my old VW bus tranny years ago... had to remember to leave it in neutral when I parked it at night so that I could warm up the tranny for 5 minutes the next morning.. otherwise impossible to find first to drive away.

Mostly it just drips out of the flange and on to your drive way... if you don't notice it then your tranny runs low and suddenly you have 5th gear issues since 5th goes dry first and overheats.

In my case it didn't leak on the bench or in the car during the 2 month engine rebuild, but started to pour out about 50 km down the road... at 10 bucks a litre it's leaving expensive puddles !

well put, thanks for that... do you need any special tools to replace them? I was told that you could just allen wrench the shafts off and pry/press the new seal in//out!  Not doing them produces expensive puddles forsure...

any trans leaks/fix where you have to drain/replenish the fluid is expensive in my opinion

Check your rear main seal for leaks.
