Been busy sorting a new gearbox into the 528i....after having the wrong one delivered. The old box blew and if anyone on here is using any variation of the ZF4HP22 then heed this warning....the older versions (3hp22 and 4hp22 with non switchable selection) WILL pack up if you rev them in either park or N. This is due to a design flaw that has no pressure relief valve/mechanism. So if you need to change the rad or bugger about with the cooling system, bleed the car only at idle rpm. Also...the E28 528i has a unique box with four bolt output flange and certain depth bellhousing. Anyway...I also painted the alloys, sorted out the MK11 3.4 and the C36 AMG which are both going to auction at the end of the month.
