Hi guys I have a crunch when im changing upto 4th (not back down) Im pressuming the syncro. I have read on a lot of sites about the GM Syncromesh and its magical powers that has stopped the crunching !!!!
I cannot seem to find it available anywhere allthough im a bit skeptical.
Is there such an oil that can help with this or have I got to just face up to the fact the box is going to have to come out and cost me a fortune....
What about the castrol syntrax ? I heard this is good but not suitable in a sti type r ?
The car is a my99 type r by the way as I think it makes a difference that it has the dccd.
Any info would be appreciated .
thanks in advance
It'll be good for your type r.
Drain the oil after a run, as it's nice and thin when warm, no flush needed. Mine had a magnetic drain plug, which i think is standard, give that a clean too.(make sure theres no big metal lumps on it!
I put in 4L in mine, and it read perfect on the stick. The rear diff takes a 1L.
When I got my UK MY97, it had a high mileage and there was often a nasty crunch when going into first and sometimes 4th. 1,500 miles ago I changed the oil, using Redline Lightweight Shockproof. It's never crunched since, totally transformed driving the car It's not cheap (£17 a litre IIRC) but it's totally worth it. I used to regularly read one of the big VW forums, and Redline oils have a very good reputation for sorting our gearbox crunches and noises.
yeah i heard the same but about castrol syntrax...
isnt it just masking the problem though , at the end of the day if its crunching then its fooked right ???
Not from what I've heard, the boxes have syncs that are funny with really slick oil like fully synth...castrol just helps the syncs work better and as long as you've not had that friday feeling crunchy for ages then jobs a good un.
Hi I have changed the oil and used castrol driveline (syntrax)
I have now covered 200 + miles since and must say the box is sweet now seem to go after about 85 ish miles and it aint come back yet !!!! RESULT...: luxhello:
Any tips on how to drain the oil from the gearbox?
Just get a bucket or something to collect the old oil and just take the plug out and let it drain.. also take the level stick out and you should be fine. Just fill it up carefully or you will get gear oil EVERY where lool and it stinks too.. fiilling the box up will also fill your transfer aswell so you dont have to worry about that. I filled mine slightly over the full mark as it is supposed to help lubricate 3rd. You should get rid of your crunches in afew miles.

do you use the castrol as an addative to the standard gbox oil, or do you put the full 4 litres on castrol syntrax in, mines a 1993 wrx import and its crunching from 4th to 5th but only when giving it some beans.
Also do you refill the oil through the dipstick or is there a seperate filler that im not seeing? thanks
yeah i replaced whole lot of oil. and refill through dipstick..
guess what .. STILL NO CRUNCHING gearbox feels totally different its transformed it in my opinion...
gonna look at putting a six speed box in next year as on the motorway it just so needs a 6th gear.....
