Just had transmission serviced and 3 days later it just all of a sudden quit working ?

Hello Crystal Riggs,

Sorry to hear of your trouble... but...

I all fairness to "them" (the folks that changed your fluid)...

You really ought to DISCLOSE why... AFTER 19 FAITHFUL years of SERVICE... You SUDDENLY DECIDED to SERVICE
your transmission...???

FOLKS generally ignore their transmissions COMPLETELY until they ALREADY have developed a problem... (the real trouble).

SOMETIMES... (quite a lot actually) a fluid change will help...

My first inclination is to tell you to immediately take it back...

And "DISCUS" it with them... To cut them FREE
have the shop demonstrate they used Dextron III and Flushed the cooler... as is FACTORY REQUIREMENT...
(repeated bulletins).

ELSE...
Give them a chance to do their work correctly.

Chevrolet Blazer GMC Jimmy Transmission Problems

Need a little more info. This happened immediately after picking it up? I mean as soon as you got home, not 2 or 3 day later?

You must have the systems scanned for fault codes before any reason can for the problem can be given.

This is caused by the blower resistor. Under the passenger dash, behind the glove box. Drop the blower motor, 3 screws and 1 electrical plug. Behind that is the blower resistor module. Cost me $31 for a new one and took about 1/2 hour to change.

It sounds like the valve body is sticking.. For the cost I would get a replacement transmission instead

sounds like a bad swich. but since it all of a sudden quit on you the blower motor could be bad as well. you can connect power and ground to blower to see if it works. if it turns then the swich is bad.

I have the exact same problem. Fuses look good, I have no idea what the problem is?

Your "wiper transmission" may be bad. Sometimes you can replace the bushings. A parts store may be able to get them for you.

the noise might be from a loose bendix on the starter,
the bendix is a little gear in fron of the starter see if there is any visual point to see it nad make sure it keeps away from the flywheel if not have the starter repalced, this bendix have a spring to keep it away from the flywheel also with a flash ligh try to see the closes you can to the center of flywheel sometimes they get crack where they atached to the engine,
and on the shifting might be a bad transmission or the shifter has to be inspected for your mechanic
