About 7 years ago when I did my carb to FI conversion on my '79, since I had the whole drive train out, I decided to take apart the transmission to get rid of the 2nd to 3rd upshift crunch. I used the "5 speed 101" instructions to disassemble and reassemble and it all seemed to go well. It's been quite a while, so I can't remember exactly what I replaced (I think it was the synchro), but it did get rid of that crunch on the upshift. I used Redline MT-90, as recommended on this forum. It was all fine for a couple of years, although only a couple of thousand miles at most. Of course, I have had a continual slow leak of the Redline that drives me nuts, but I top it off from time to time. Anyway, for the past couple of years, it has developed a crunch going from 1st to 2nd and from 3rd down to 2nd. Not everytime, but at least 50%. I just haven't had the energy to deal with dropping the transmission again, but I have been driving the car a lot this summer and I am really getting tired of the crunch (plus the endless Redline on the floor). I am going to put the K20 project on hold for a while and tackle the '79 transmission issue, but am looking for advice on what I should be looking for and what I probably need to replace. Since I will have the drive train out, I am also going to be changing the rear wheel bearings and doing a total brake system refresh. One last question regarding the shift linkage. The '79s have a unique shift rod and linkage to the transmission that does not use the lollipop. I have the shift rod from the '81 K20 swap car. Is there a significant difference in how the shift linkage feels with the lollipop as opposed to the hard linkage of the '79? Since Fiat when back to the lollipop after the '79 run, I am wondering if it is a better solution. Since I will have the transmission out, it seems like a good time to change the shift linkage while I am at it. Thanks for any advice.
