Accurate transmission diagnostics is the key to a successful transmission repair. At some point every transmission will let you know it’s had enough and start acting up. To solve your transmission’s issues they must first be diagnosed correctly, you’d be surprised to learn how many auto repair shops misdiagnose transmission problems. Not only does this lead to an unneeded repair that just masks an issue, but without accurate transmission diagnostics the un-repaired issue can turn into a much larger and expensive problem.
