The form starts off with the easy stuff: name, address, etc. TREMEC will use this information to send you your shifter ball. Next, the form asks for information about your transmission. Your purchase date can be found on the invoice you received from us and you'll know the installation date. Be sure to select "Silver Sport Transmissions" from the drop down if you purchased from us. It will then ask you which transmission you purchased. If you're unsure, it will be one of the first items on your invoice. It will either be a T-5, TKO (500 and 600 are both listed as "TKO" on this form), Magnum (most people will have this version of the 6-Speed), or Magnum XL (almost exclusively for late model Mustangs). If you purchased an A41 Automatic, it is not a TREMEC transmission and does not need to be registered with TREMEC.
Once you choose which transmission you purchased, a new form will come up to get the information off of the metal tag on your transmission. Below the tags are highlighted in the images of the transmissions. On Magnum transmissions, we will often move the tag from the upper passenger's side bolt to the lower passenger's side bolt, so your transmission may have the tag in one of those two areas.
