Hello again,
I'm looking for some advice. I have a 1975 International Scout, which has a 727 as the automatic. I rebuilt the transmission about 10,000 miles ago with a kit from SMR up in Canada. It has worked perfectly since the rebuild. However, on the way home from work last week, I put it in reverse to back into the garage and it shuddered. It was not just slipping. It would grab, release, grab, release, etc. I drove it around the block to test it, and it was a consistent shudder in reverse only. Not knowing what to think of this, I parked it and went on the internet. Based upon what I read, I thought it might be that the low/reverse band was a little loose. I pulled the pan and adjusted the low/reverse band. I torqued it to 72 inch pounds and then backed it off two turns. Before I did this, I marked the head of the adjustment screw with a sharpie, and I noticed it took about 2.75, or maybe 3, turns to hit 72 inch pounds, so I figured it was loose. So I torqued it to 72 and then backed it off two. I drove it, and the shudder was gone, but now there was a rattle on the 1-2 shift. It backed up fine and also drove fine in manual low. I did some more research and I figured maybe I was a bit off with my 2 turns, so I took the pan back off and simply backed off the adjustment screw 1/4 turn. It sounded like perhaps the low/reverse band was just a touch too tight and it was holding low when I went into second, thereby causing the rattle. I did not re-torque it to 72. I figured that when I adjusted it the first time, while I was on my back, I simply thought I backed it off 2 turns, and I was off by just a 1/4 turn. After backing it off by 1/4 turn, I just put it all back together and the shudder is still gone, but the rattle on the 1-2 is still there. I am beginning to wonder if it is something other than the band? Any suggestions? Thank you in advance.
