'90 S10 Blazer automatic not shifting gears
 

Hey guys,

I hope you're doing great. I have a 1990 4.3L S10 Blazer, automatic 4x4.
The car was working relatively fine until today. Started the car, drove it for 5 miles and made a stop for a few minutes, just to find out it was not shifting gears any more.

The car stays in 1 gear despite switching overDrive, Drive, 2 or 1. Reverse is working. If i give it more gas it revs pretty quick. It has never had any slips between gears.

Can this be a shift solenoid problem or maybe a blown fuse for the solenoids (i am not sure if this older models had a fuse for this solenoids)? I am affraid the transmission could be dead :confused:

I am not experienced with automatic transmissions; had to research and read a lot on this today due to this problem to get a better idea on what to expect when taking it to a repair shop.

Any information or tips you can provide are much appreciated.

Thanks in advance,

Did you check the fluid?

if the speedometer isnt working it could be the vehicle speed sensor.

my 93 has some goofy issue where it keeps popping the ign/gau fuse, but when it does that it goes into 2nd gear until the fuse is replaced
