First is gone ... grinds going in, pops out when I let the clutch out.
I've done lots of linkage adjustments, replacements, etc. etc. Followed the Pelican Tech article to open the tranny and check out the gears. This is what I see... dog tooth: slider: I'm assuming I'll be replacing the syncro ring, and the dog tooth gear. And the slider is still ok. Yes? No? Any recommendations on where to pick up the parts? |

I think you can find a slider for just under $400. Sorry to tell you that but that is reality. I posted some pictures of a new one once, it was colser and crisper than your pics. If you can find them maybe you can deside if it worth the money.

I'll sell ya a first gear with good dogs & syncros for 100 bucks. Your slider looks remarkably good considering the condition of those dog teeth. Considering the price of a new slider ( if you can find one), I'd get out some files and work on that thing.

Thanks Jeff. But putting it all back together w/o leaks is the true test. |

The back end of the tranny's are not that bad for leaks. Make sure everything is clean and use a good sealer like yamabond or red permatex (565 I think)

The factory gasket is better and cheaper than a tube-a-goo...and you can get the end cap off next time.... (IMG:style_emoticons/default/biggrin.gif)

Your slider is remarkably in good shape. You can get a way with reusing it. I can send you a used 2-5 set of teeth that you can use in 1st or you can buy a new 1st set of teeth. I also have some good used synchro bands. You are lucky with that slider.

Make sure everything is clean and use a good sealer like yamabond or red permatex (565 I think) Guess I should have clarified. I use both, when using the sealer, I go very light, just enough to make a seal but not to squish it into the case. The permatex red is anarobic so it comes apart with no problems. |

You DO NOT need any sealer on the nose cover gasket. The Cap'n

Sealer use on the transmission is verboten! No, no, no!

On mine - both the end cap and the intermediate just had goo - (white - looks&feels like silicon) - no cork-type gasket.
It worked fine - no leaks. While knocking the end cap off, the intermediate slid out a bit too. So, do I need to re-goo the intermediate? Or will it seal? ---- Thanks Dr.Evil for the opinion on the slider - you made my day. |

OK - odd timing w/Dr. Evil there. So can I put a cork gasket on the intermediate without dropping the tranny? |

The gasket (paper) between the intermediate plate & the case sets the pinion depth. The gaskets come in 2 thicknesses.....010 & .005" (round numbers in inches). Should the gasket be replaced, always use the same thickness as what is in there. Pulling the gear stack with the trans in the car is "a bridge too far" for me.....getting it back in, actually.

No cork, only paper. They come in various sizes from .009" to .022". Generally you can make the right thickness with the gaskets provided in the kit as there are 3 of them. I have plenty of case to intermediate plate gaskets, but no intermediate plate to tail cone gaskets as those get used up in every build and you can not buy them separately. IF you MUST pull the tail cone, AND you dont want to buy a whole seal kit to get the gasket for it, THEN you CAN use some sealant. It is not a precision fit so the dimension is not a big deal. Having the paper gasket separating in front of the intermediate plate is not a big deal. Just reassemble things and it should not leak, UNLESS it was assembled with goop before. If goop was used you might as well pull the stack and replace the seals after cleaning the surfaces. Otherwise, you risk having leaks, and pinion misalignment.

Reasons:
1- it is unnecessary, the paper seals have held their own for 30 or so years with no sealant. 2- it is a potential for tolerance goof ups 3- it can get into places where it should not be |

I'm going to disagree with the others. Replace the slider. It has taken a beating and burred over. No way to measure the wear and could easily ruin the new syncro and you'll be right back at it again. I do however error on the safe side.
I once pulled a 901 out 3 times because it wouldn't shift into first correctly. It had a slider that "looked" perfect but was too worn to operate correctly. You never regret doing it right..... |

With a good band and teeth, I have never had issues using sliders in that shape. I advise the owner of their options, of course, but the $500 price tag tends to make most open to using good used parts.

Try calling Carquip and ask for Tom for a good used one or hell I have bought decent used trannies for $100.00 to get a few parts. |
