I have a 1976 300D 115. My trans had been slipping for the last year and I expected it to go out, well it went out (at least close to home) and I put a deposit on one at a local junkyard. I was able to remove all the bolts except the 10mm hex bolt above the starter. Now I am stuck. Any suggestions as how to best remove that last bolt? am I getting in too deep? will I be able to swap the trans? in the meantime I found a 1979 300SD 116 that is super clean with only 156,000 mi and now have the time to fix the old 76
