New to the forum. Just purchased a used 07 L48. States low hours (260) and machine seems to be clean to reflect this. Cannot be 100% sure as always. Speed in high gear moving forward is slow at best. Reverse is very fast in high gear. Trans service is recorded on filters as being done at 202 hrs. last year. My thoughts are to do a full service (filters and fluid) on trans to be safe. Anyone have suggestions as to cause of slow speed in high forward and what else I might check?
