1996 Jetta won't shift into drive all other gears

change fluid start there

show it to mecanic and change the part

If the transmission will not go into gear or has trouble finding gears and has the proper amount of fluid, the shifting linkage could be bent or misaligned, especially on automatic models. The linkage can be found on the driver side of the transmission, toward the top of the unit. Inspect it to make sure the components aren't bent or broken and have someone shift the Grand Cherokee while you watch from underneath. Most times, only minor adjustments are necessary.
Also, check Torque Converter and scanned the TCM (Trans Control Module) to know if some fault code is stored there.

IF engine lack of power gear will not change repair you engine first . make sure engine is ok then check gear

Hi is this a jetta 4 or 5
If jetta 4 you have to look at the glowplugs itself
If ok check fuses
If ok replace Glowplug relay 103

have shop road test and scan possible solinoid

safety switch on brake pedal. common cause is a wire breaking off. there are 1 to 2 wires going to this switch. It is located on the brake pedal bracket above the foot pad.

you might have bad ground to transmision that happen to my 01 jetta were it would just kind of rmp no shifting gears dealer said it was bad ground to trany

VW Automatic transmissions must be filled within a specific level or they will not shift. Also, must have VW special transmission fluid or ATF +4 FULL SYNTHETIC!!! Required to create proper internal pressure...

wha???????????
