Pulling the front pump on 4.5 transmission

I'm getting ready to drop the transmission from my 280SEL 4.5 to replace front seal and the front pump seal (o-ring). Anyone done this? Is there anything that needs to come out of the tranny prior to pulling the front pump? Anything else to do while I'm there? Hoping to fix the flood of tranny fluid landing on my garage floor. Leaking about 8 oz. per week to 10 days.

Haven't repaired a tranny personally. However, look at the online resources portion of the forum. I uploaded some Mercedes repair manual articles about our trannies...

Grubeguy,

I did look at the uploads you have on the resources portion of the site. Not a lot there in terms of tear down and rebuild. Even my Mercedes manual skips the whole transmission topic pretty much.

I'll post results if they turn out favorable.

Thanks
