Rear Main Seal Part Number

[fastd]

Just replaced rear seal but looks like I still have a leak; I had to pull the tranny again for other reasons so will replace seal again. Didn't replace the side seals; will do those later. I didn't grease the main seal before I installed the first time; so since the tranny is out again, will do it right this time.

Called Nissan to ask for the seal but they have two different part numbers: 12279-2B500 and 12279-R4611. I have a 260z block - any opinions about the right part number?

Also, is Nissan geniune replacement seals the best seal to reinstall? Better luck with Felpro or others?

Thanks.

fastd,

change your side seals I had a leak that I thought was the rear main and changed it 3 times and it still leaked, after changing the side seals no more leak... I believe I used a fllpro seal and it came with the side seals.

The part numbers you are quoting dont match the original E-Fast system. The E-Fast system is quoting 12279-21003, 12279-21010 and 12279-R4600. The number 12279-R4600 was changed to 12279-R4601.

I used rtv on my side seals and the inside edges of the block. No leaks so far. Whoever, replaced them the first time left it dry and they eventually leaked.
