Pin bushing housing.. what is it?
 

My c43 transmission is leaking. The shop says its the pin bushing housing and wants $300. What it this, where is it, and how bad are they sticking it to me? They just did a tranny fluid swap.. is that something that should have been corrected during the swap? It didnt leak prior to the tranny fluid swap.

The quote says parts $5.75????? the rest is labor and fluid!

Buy part number 203-540-01-53 & install it yourself.

ONLY tools needed are a 7mm socket & ratchet.

It was some sort of electrical connection inside the tranmission they described as a linkage. They just told me they had to drop the pan to get at it. I guess thats where the $300 comes in. I wish they would have done that when they had the pan off for the service!!!!

In American-speak, Mercedes uses "bullet-style" electrical connectors.

Pin bushing housing is their term for the female portion.

A 25-cent part.

trans leak
 

this is common.the part is on the top pass side of trans at front.disconnect electric plug and down inside conduit there is 7mm bolt.make sure new part has new o rings when it goes back in.

thanks all. sounds like $300 is way over the top. :( 1 hour labor should have been max = $95 -$120 at most. Sigh, I thought I had found a good honest shop to work with. Live and learn. Guess I should start fixing my own stuff again.
