I had no idea whatsoever about RMS and IMS. Now that I found out I went through the service history and found out that the British "Renew rear main seal and IMS seal".

Does anyone have any idea what that means? Do I need to replace IMS or is the job done by the previous owner?

Many thx!

Sounds like they updated the IMS outer seal to the triple seal. This has nothing to do with the IMS bearing only the outer seal to prevent oil leaking out of the engine case. Hopefully the RMS seal is the latest version introduced in 2005 which is normally leak free indefinitely. For more info on the IMSB search the forum.

Just to let you know, the cost of this so called seal, was at 1000USD at the time (2006).

Quite high isnt it?

Current USA cost for RMS is $15. IMS mounting flange with updated seal is $150.

$1,000 is typical labor cost to remove transmission & install seals.

You will get more responses in the Technical forum thread. OPA!
