You likely attached the linkage wrong at the tranny. The plate that bolts to the ears on the tranny can be bolted to the wrong side of the ears quite easily. When you do it wrong there is not enough travel available to bet all of the gears to engage. With the shifter in neutral, look at the rub/wear area on the shift rod at the tranny bushing. You should see an equal amount of wear/rubbing marks on both side of the bushing. If not, take the 2 bolts out and move the plate to the other side of the ears. ~~~ I will add one more note to the wisdom above. Make sure that there is enough "float" in the shift linkage. As the van accelerates and decelerates the transmission moves forward and aft. If there is insufficient float, second and fourth gears can run only partially engaged and will wear out very quickly. A transmission R&R done at a shop not to be named forgot to check this all important item on a transmission that I had just had rebuilt. Fourth gear failed after 1600 miles and began to "pop" out of gear under acceleration. Cost me another rebuild and the shop refused any help in the matter claiming the shift linkage is "not adjustable". Not so of course. Anyway inquire of a good rebuilder how to determine this float. The defect occurs when the plate to which mark refers pushes against the shift rod slightly enough to partially disengage the gear under load. I highly recommend as I have done in the past, Jeff Field at Transaxle Engineering in Chatsworth for consultation and repair. He did both rebuilds for me and the second one is doing just fine after a bazillion miles with a properly adjusted linkage. |
