anyone know where i can buy some frictions steels
I need 5 @ .060 for direct and forward
The friction kit only came with .090 steels
Thanks in advance benno

Are you after .060" steels or frictions.
You can get them at all the trans parts suppliers.

I'd opt for the thinner frictions and thicker steels.

If you have the steel 3 piece pistons then you probably need to look at the spacers to get the clearance you want.

Use alloy pistons if you can get them.

[benno81]

Ive got all alloy pistons
Im at .040 clearance on both drums
So i was hoping just to change 2 steels in each
Im in brisbane any contacts my way?

[GtoGeoff]

Driveline in Sydney should have them, ph [02] 9896 6811

Machine the pistons would be my preference, it is more desirable from a thermal point of view if you can.

Motospecs have .060" forward/direct steels

[benno81]

Its around 2 months wait before any of the machine shops (ones that i trust) can machine the pistons for me
Have u got contact details for motospecs?ive never heard of them
Thanks alot for ur help

Ahhhh...... been living in one of them afghan caves.

Fairly large company, own Repco, Approved and others. If you have a Repco account it should cross over.

Just drop them down to any engine repair shop, transmission shop and ask them to take a cut.
Only takes a couple of minutes and it doesn't have to be precision.

Part Number. JCS-4000

[Gregaust]

JCS-4000 I have listed at 1.95MM OR .077"
The JCS -4001 IS 1.52MM
JCL-4030 Is the listing they have for both High + forward frictions @ 1.55mm

[HQ 368]

Yeah, not bad for my memory I think, it's been at least 2 years since I bought some.
I checked Gateway, says JCS-4001 is .060" like you said.

[Gregaust]

Glad you bought it up actually , I'd not noticed those in the listing, not that I've needed them usually use the thicker steels

[benno81]

U guys able to tell me when going from a tci to trans specialties
Rmvb can i leave the check ball that is jammed into the acummulator from the tci in?

[HQ 368]

Are you talking about the accumulator in the valve body or the case ?
Which valve body do you have ? with or without engine braking.....

If the TSI one does not mention it in the instructions and the case port is blocked, just remove it and be safe.
They usually leave it redundant and ask to take the sealing rings off.
Another one to watch for is if an exhaust has been created by removing a gallery plug inside the case where the intermediate clutch sits.

Accumulator drain
The problem is damaging the casing getting it out
Ive asked tsi they just sent me the instructions for the valve body

[HQ 368]

It's not really a drain, that is normally the intermediate clutch pressure being directed to the accumulator.
Follow the passage back to where it meets the valve body and see if the separator plate has a hole to feed the port or not.
If TSI plate does not have a hole you may find you can get away with it still in there. My concern is that cross leaks always occur and pressure will build up in the passage and may cause another problem.

If it was me, I'd heat the case and bolt a plate over the port, pressurise with air until it comes out. Heat it with MAP gas or your bbq gas, Oxy may melt the case if your not careful.

If you look inside the case you will see a gallery plug in line with that passage, in many cases you remove this plug to create an exhaust.
It is good practice to exhaust to atmosphere any passages you make redundant.

Try and stick to the TSI instructions
