Hi everyone I recently pulled my 4r100 tranny because reverse had gone. Everything els worked still worked. You could drive the truck just fine . Just couldn't back up. I replaced the reverse steels and fibers which were welded together. After I put everything back together and bolted back into truck I had fixed the reverse problem but the truck won't shift anymore. All my gears work on gear selector. But when put in drive it won't do more than 30kmh. I pulled my shift solinoid and tested it and it seems fine. Pull main valve body and checked everything seems fine. Please help
