There's so much talk of fluids and the correct type for what box Jim that it isn't funny. Good ole' AlanS will be looking down at me and laughing, 'cause I am beating the drum he so faithfully rapped for years.CitroJim wrote:Thanks Oz, brilliant.OzRX4 wrote: The ELF RENAULTMATIC D3 SYN is what Renault recommend for the same transmission, i.e. DPO as per Renault nomenclature. {I'd paste the file but as I am a computer fool I can't
Here's the Elf Spec. sheetand as the DPO and AL4 is one and the same 'box, that's an excellent discovery. The Elf stuff should therefore be OK in the 4HP20 too if the Mobil/Esso recommended LT is not available.
I've got on file here somewhere a ZF spec sheet for oils for all their boxes and the 4HP20 does have different requirements than the earlier ones.
Here's a link to a USA based re builder who has parts and a forum for discussion and questions about transmissions. He seems to know his stuff and was puzzled when i mentioned the problems associated with the boxes on Euro cars. Here's the link for Cobra transmissions, you'll have to have a poke around for the forum.

Can't locate the ZF files, will look further.
