Got it 99% back together. Just adding fluids and bleeding the clutch. Hmmm clutch isnt feeling "right". I look under the car and there is brake fluid leaking out of the bellhousing. Yep, HTOB is leaking. WTF? This car is cursed.

Clutch discussion:
http://www.fiero.nl/forum/Forum2/HTML/131391.html

So now what? The previous clutch worked just fine. The original HTOB worked just fine. I add a new 3+ clutch, SCS883F, posted above, I get the HTOB spacer that is suggested for the clutch kit, put it all together and it leaks. I am at a loss. Do I rip it all back apart and put the original HTOB in and try bleeding it before putting the engine back in the car? If it leaks, then what? I am this close to putting a 4T65HD in it and call it a day.

MotherF&*()^&%^ car!

Are you 100% sure the fluid is coming from inside the bell housing?

Yes, its coming out of the square notch at the bottom of the trans by the flywheel. :/ I am going to try to check the HTOB tomorrow before I start to rip it apart.

After having the F23 swapped into my car, it started leaking from the same area within a week.

Turns out the bell housing side of the tranny case had a crack in it. Had that side replaced and all is well now. Hope you get it fixed soon!

On my first use of a HTOB back in 2005, I over extended it right when I pressed the pedal. From that day on I never install a HTOB transmission w/o confirming the range of motion of the HTOB and the current placement of the clutch fingers. This will let you know pretty quick if there is an issue or not. Also, as soon as the cradle is in the chassis, the very first connection is the HTOB. Then I test cycle the clutch about 10 times just to verify everything. Only after the HTOB checks out, do I finish hooking up everything else.

There is a lot of variation is clutch disk thickness and pressure plate design both of which change the finger position at rest - even among the same MFG.

Once you get everything worked out and issue free, you will never want to go back to the Fiero slave cylinder. The HTOB's are quite nice.

As the owner of a later Getrag with the HTOB, I'll second this opinion.

It worked great with the old setup. I didn't use a HTOB spacer with the "incorrect" getrag clutch. Though I was told I would need a spacer with the new clutch I installed. I need to call SPEC and see if there is a hieght difference between the 2 pressure plates. Maybe I just got a faulty HTOB right out of the box? Who knows....

You replaced a know good HTOB with a bad one?
