rebuilt transmission rating collinsville il

The folks at Marshall’s were fantastic!  Scott and his team had me in and out in under 48 hours with a full transmission rebuild when I was passing through the area on a military move from New Jersey to California.  These folks really got me out of a jam and to top it off Scott is a man of his word!  He has stood behind his work.  I had a minor issue with an intermittent sensor wiring issue after I left the St Louis area and Scott covered all the costs for the wiring and sensor fix.  There was no difficulty I just called the folks at Marshall’s and let them know what was happening and they worked out the payment with the servicing shop for the sensor and wiring.

Thanks again for being a man of your word Scott Marshall.

I have a modified ’67 Camaro that was very difficult to drive due to issues with the clutch, transmission and assorted components. Scott and his team took to the challenge and corrected one issue after another; even going to the extent of machining a 3/16th inch plate to create the space to get the correct clearance for the hydraulic clutch. Driving my car has gone from being nerve wracking to a true joy! After this experience I would absolutely trust these guys with any of my cars.
