93 dakota 5.2 flexplate auto trans
Hello. If the transmission is removed, then replaced, how critical is the position of the flex plate, relative to the cranks sensor. Does anybody have some experience with this? It's a 93 dakata 5.2 automatic 518 lock up.

The flex plate can only go on the end of the crank shaft one way and it can only be bolted to the torque converter one way as well. So in relation to the crank sensor, you can't mess it up. What you do want to make sure you do is mark which way it bolts to the torque converter so you can have it lined up when you put the transmission up there. That will save you from a big headache.

Thankyou. That gives me some piece of mind. This little green "tank" of mine has been troublesome. It has been my project for quite a few months...barely moving. I think my problem is the crank sensor. It runs briefly then seems to flood out and quit. I just pulled the sensor today. Should I be looking for some kind of mark on top of the flex plate?

The flex plate has 8 holes in it on the v8. When the sensor passes over one of those holes, it sends a signal to the computer to unground the ignition coil. But those are the only "marks" I can think of.

Well like I said, the flex plate can only be mounted in one orientation because of how the bolt holes are drilled, so each hole on the outer edge of the flex plate corresponds to a particular cylinder with the piston at firing position... so technically it does matter which hole it passes over, but you have no control over it so you can't possibly get it mixed up!

Thank's for imparting your knowledge. I'll be fresh at the task tomorrow. Hopefully, I'll be celebrating its rebirth soon.

Hello again. Before I install this new crank sensor, I gotta question. Should continuity be present on all three prongs of the connector? I believe the conductors would be current, ground, and signal. Got any suggestions? Thanks

This is all the FSM says:
CRANKSHAFT POSITION SENSOR TEST
To perform a complete test of this sensor and its
circuitry, refer to the DRB scan tool. Also refer to the
appropriate Powertrain Diagnostics Procedures manual.
To test the sensor only, refer to the following:
On the 3.9L/5.2L engine, the sensor is located on
the top of cylinder block near the rear of right cylinder
head (Fig. 1).
(1) Near the rear of intake manifold, disconnect
sensor pigtail harness connector from main wiring
harness.
(2) Place an ohmmeter across terminals B and C
(Fig. 2). Ohmmeter should be set to 1K-to-10K scale
for this test. The meter reading should be open (no
resistance). Replace sensor if a low resistance is indicated.
