Location of checkballs on 2000 and later vehicles using the A340E, F or H series of transmissions is, at best, one of the most-difficult issues in the transmission industry today. The main reason for this is that checkball locations vary among vehicle models, model years, engine size and whether it is two- or four-wheel-drive, the latter being the most difficult.
Because of constant demand for this information, we at ATSG are going to expand upon this information with one condition: If in using this material you find a variation that is not illustrated here, we hope you will let us know as soon as possible so that we may keep this information as accurate as possible for the good of the industry.
