Valve Body Training

[badsect0r]

Nice pics, Jason. Thanks in advance for pics and DIY instructions when you start with the 4HP22 of your 535.
Is it difficult to source ZF parts in Australia? For example the main gasket or in case a sping in the valve body is broken?

Initially I tried ZF Australia. They were willing to sell me a full transmission rebuilt kit only, AU$179.00. I asked them if they could supply the main gasket for the valve body by itself, they had no stock and no ETA.

After talking to a few people at local transmission workshops I was pointed in the direction of Motospecs. They were able to supply 4 different versions of the main gasket. Three were listed for the 4HP22 and one for the 4HP22EH, as they could not tell me which of the three I needed for the 525i hydraulic version I got all three. They were about AU$5.00 each. It took them 24 hours to deliver them to me via courier:-

Part # : Application
ZG-4005 : 4HP22
ZG-4025 : 4HP22
ZG-4105 : 4HP22
ZG-4205 : 4HP22EH

As it turned out the main gasket in the 525i valvebody was in perfect condition and I was able to reuse it. The whole thing was pretty clean really. The car had done 254,000Kms, I do not think the transmission had been serviced previously and was working perfectly when the car met it's untimely demise.

Photo below, the 4HP22EH gasket is in the lower left of the shot:



The Pan Gasket and Filter can be had from pretty much anywhere, all the local chain stores such as Repco, Autobarn, Supercheap & Bursons carry them. The cheapest I found was a wholesaler by the name of Imparts.

Filter was AU$14.92 and the Pan Gasket AU$8.82. Part numbers are clearly shown in the photo below:



I won't know if I need anything else at this time. Once I get the 535i unit apart I'll know more. I am hoping it's simply blocked, but if I need a checkball or spring, I think Motospecs will be my supplier.
