Getting ready to place an order for parts for my transmission rebuild and was looking for opinions on which of my synchro rings are good enough to flip.
In the picture the order they came out of the transmission is 1st, 2nd/3rd, 4th/5th. It's obvious that 1st is done. 3rd looks to me like I could reuse it, very little wear. What about 2 and 4/5? The coating on 2 is a little rounded at the peak. On 4/5 the moly coating is worn just past the half point of the peak. Would these be considered good enough to flip or should I replace them? Attached image(s)

Thanks Marlo for the great pic's for us who might be doing this rebuild.
??for the Experts: Is this a normal pattern to see in most old trannys? Why is #3 so perfect - normal wear? or was the driver someone who skipped 3rd gear a lot? (IMG:style_emoticons/default/confused24.gif) Thanks. |

That may not be the 3rd gear synchro; it could be 2nd gear. When I pulled everything apart I was careful to make sure I kept everything from 1st, the main shaft, and pinion shaft separate but I didn't mark which synchro was 2/3 or 4/5. So the third synchro in the picture could be either 2nd gear or 3rd gear. And I have no idea what kind of mileage was on this transmission. I was told by the PO that it's the original transmission to the car and there was an issue, but can't remember what he said the issue was. |

[/quote] ....................so the information you provided to us in the second sentence of your post is incorrect?....the sycronizers are not in order of removal...1st thru 5th.?..........generally you can reuse 3, 4, 5.....if in your case you can figure out which is which. [/quote] Yes, I did not mark them when I removed them (should have). That's why I grouped them as "2/3" and "4/5". |
