or give us the trans code off the door tag. That year behind the I-6 it could be a ZF-5-S42, or a Mazda M50D. Both were used in a lot of trucks for a lot of years, so parts are available. Parts for the ZF are more expensive, since there aren't as many of them.
Unfortunately the previous owner took off the door tag. So I can't provide that. Sent from my HTC One S using Tapatalk 2
