Tried forever to install strut with no luck, finally brought to guy who built it for me and he was not able to install it either. He said,I assemble the band strut assembly before I put low reverse drum in, so he gutted the trans and started from the beginning. Took him only 45 minutes take apart and reassemble. Everything ok now. He said it may have been that the band is new and is just a tight fit. Again this transmission has never been ran since rebuild!
