bad now, will update when made right
for starters, the gear selector shaft is so short and stubby, you wont be able to fit the gear sensor on it .(not a problem for me, because i'm using Fitech Goshift Trans controller) however, you're going to have to modify your shift linkage. after installing the transmission, it would not shift out of first gear, and the speed is not reading on the dash. to troubleshoot, i switched the vehicle speed sensor with the one from the old transmission. when i did this, i found that the new transmission is missing the vehicle speed sensor reluctor on the internal drum! this is only possible if this 2WD trans was rebuilt, using a 4WD drum, that has the speed sensor located on the transfer case, or if they simply simply tried to pass off a 4wd trans as 2wd by swapping tailhousings. needless to say, i'm near $2000 out of pocket, PLUS the labor to remove the old trans, cost of transmission fluid, and the labor
to install the new one. now, I have to remove this one, and have my work truck down until this is all resolved. customer support was responsive, and got me to a tech to verify the issue, and they sent a return authorization. i'm sure it was all just an honest mistake, but now i'm going to be out close to $200 in fluid after its all said and done, and i cant make any service calls until i've got a new transmission. just a bummer of an experience.
