I have swapped in a 3.93 geared transmission to mate to my quad 4 that uses a hydraulic throwout bearing, and this is what the attachment point for the hydraulics looks like on the transmission.


But the adapter I bought from a guy in Florida who makes them for ecotec swaps, looks like this.


Does anyone know where I can get the proper adapter? Thanks for any help.

What transmission is that? Or what did you grab it from?

Or, you can look here for more options

EDITED to Add: The part number I've stated above does not fit! I had purchased the Mcleod line some years ago and I had forgotten that I had to cut off the quick disconnect fitting and used the fitting from a Pontiac Sunfire instead. The Mcleod fitting is longer and will not lock in place.

I am assuming the Mcleod 139204-xx directly connects to the hydraulic throwout bearing's adapter from your description?

Look on the backside of the plastic fitting and you should find a nut. Remove the nut, toss the plastic fitting and then you are left with a 1/4" inverted flare fitting.

Yeah... unfortunately that adapter will only work on 2000+ transmissions like the F23 and F40. Just a note for anyone else who finds this thread.

Except the flare on the end that connects to the Fiero hard line is incorrect. This adapter is for an inverted metric flare and the fiero line is a bubble flare.

And sure enough on the end of the stock fiero clutch line that I broke off, you can see where the inverted flare was pushing down in the center of the bubble flare.


I have never seen this mentioned in any F23 thread, so I am starting to think that all (or most) of them have been installed with the wrong flare on the end. I used my flare tool to modify the bubble flare to better seal with the inverted flare surface.
