When I took my transmission apart last summer to try to replace it, I found that the coupler had been put on flush with the shaft end. The new transmission I got required the coupler to be slightly offset so there was a depression for the transmission coupler to seat flush with the shaft coupler. I have tried all winter to get the two nuts loose that hold the shaft collar in place and could only get one off. I am giving up on that project for now and I suspect that even if I could get the nut loose, the coupler is likely to be unmovable, so likely would require replacing the shaft. I am curious, since you just did this if the shaft coupler was recessed? My transmission consultant said they should always be put on so it is not flush with the shaft. Do you know if yours was flush or recessed? Dave
