crunchy 2nd gear on a 265

[x_atlas0]

Hey, guys.

The 2nd gear on my Getrag 265 is pretty crunchy. It has new stock weight fluid recently, as I was uncertain the last time it had been changed, and was filled to capacity. It is very difficult to get it into gear, and once it does, it makes a fairly loud "thud" and has no resistance to the rest of the gear. None of the other gears are like that. Based on the description of the operation of synchronizers, it would seem like that is the failure point I am experiencing, but I wanted to check with you guys, since you have far more experience than I in such matters.

Thanks!

This sounds more like a selector fork problem rather than a worn syncro hub+baulk ring, from your decription of the noise its a little difficult to be 100% sure. What I am sure about is that the box will need to be stripped down to repair it. I've never had to stip one of these boxes but from what I understand they are a little tricky to do and some special tools are required although I'm sure someone on this forum said they were making the tools required to do the job, or maybe I'm going mad and just imagined it.

I am in the process of getting my 265 5 speed reconditioned - very few (i.e none) transmission places where willing to assist - special tools required was the reason they provided. Eventually tried another approach and sourced a shop who specialise in preparing/repairing race car components - they took the job on without blinking an eye and where very competitively priced as well - - estimated it was 10-15 hour job to strip and rebuild - I get the box back next week so hope all goes well. BTW I sourced the components - bearings, synchros from JAYMIC in UK . Figured while it was open I may as well replace as much as I could afford.

Well, guess I better start saving my nickels and dimes for a Blanoton rebuild.

May be...

Simpler to get another trans than to have Blanton or other, rebuild it. Seems to me his price was posted here not long ago...

One thing you can do, temporarily, is switch to a 50:50 mix of ATF and 90 weight. This is the old 2002 SOP for crunchy 4-speeds. Long term, it's a little hard on the bearings, but helps the synchronizers work a bit longer.

I use Red Line MTL. It's probably the equivalent of ATF and 90 weight. I have been running it in my 265 for years.
