I want to reseal the gearbox, I mean, put in new gaskets and oilseals. I got all seals and gaskets but to me, the seals look awfully thin, made of paper. Would this be enought to seald the 35 year old gearbox? Or do most of you use some liquid sealing compound, if so, which one is best?

Ad,

I did this with my '90 GT. Yes the gaskets are very thin, but they should seal. I used "Form A Gasket", nevertheless. Everything turned out perfect. I don;t know if you have this in the Netherlands but I'mmsure there is something equivalent.

Those paper gaskets do a great job of sealing...if everything is flat and perfect.

I bought a group of brand new transmissions that had been sitting for over 20 years, full of gear oil. Every single rear differential gasket is completely saturated and has some signs of leakage.

A light coat of Curil K2 on those paper gaskets works very well and should be a very common sealant. in Europe. That's what I use, here.

Thanks, That Curil K2 seems like a good idea, although the surface is flat and clean (cleaned both surfaces with scotchbrite). The paper on its own just sounds too good to be true.

The reason I took the lid of the gearbox is that I wanted to see if I had those dreaded fingersprings that break and leave steel parts running around those precious gears. Apparntly my gearbox has a different spring setup.

I pondered this too when I had the trans out of my 89 while fitting LSD to it and using a gasket set.

In the end I used hylomar spray to give a light coating on each side of the gaskets, on the basis that if the paper ones didn't quite seal and I had a leak, it would be a major pain to drop and reseal the trans (I have no hoist in the garage).

I shy away from using RTV/yamabond/etc. to glue my car's mechanical bits together.
