Transmission misdiagnoses are commonly discovered at Suburban. I can share our experiences with you as they apply to your specific vehicle. I have documents to support the countless occurrences of what was later explained away as “honest mistakes”.
Terence Brown called me concerning his Jaguar XJR. His car was at another shop and he was told the transmission had an internal problem and would need to be removed and disassembled. We discussed the problem, I gave him a worst case price, and he had the car towed to us. Upon inspection, we noticed the vehicle had a leaking transmission cooler line. We replaced the line, added fluid (3.5 quarts), and test drove the vehicle. The transmission operated properly, so we delivered it to the customer. Total cost was $185.00. Because this rare model came with a Mercedes Benz transmission, my initial worst case price was over $4000.00. That’s quite a savings. While the other shop’s misdiagnosis could have been an honest mistake, it still might have cost the customer thousands of dollars. Even more alarming is the fact that the vehicle was driven 17 miles while at the other shop, while 3.5 quarts low of transmission fluid! Had we found it needed a transmission, it might have been have been the other shop’s fault from driving while low of fluid. This is not an isolated case. We have caught similar misdiagnoses on numerous occasions to the customer's relief. While I will not publish the supporting documents on the internet, I will be happy to show them to you in person.
