Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Manual transmission:
Manual transmissions tend to pop out of first gear because the transmissions were built without a detent ball and spring. Under warranty, these parts will be installed. (1999-00)
Vehicle shake:
Extended cab, long box models shudder when accelerating from a stop requiring replacement of the two-piece driveshaft with a one-piece driveshaft. (1999-01)
