I'm trying to find the actual TSB issue'd from GM regarding the Allison gear indicator problem-

here's the info I have..

Service Bulletin Number- 020730011A
Bulletin Sequence Number- 634

Date of bulletin- 05/02

I have tried going to the techlink.gm thing- but i can't get into the archives. it will only show me the oct '02 pages...if ANYONE has a copy of this- with the actual "this is how you fix it"..please either post it here- or email me at
twozenuf@sover.net
