Check to see if you have a vacumn pipe from inlet manifold to the gearbox on this age vehicle as if this pipe is perished or disconnected it will not change gear properly

Ther are so many things that can cause hard shifting, heres a few things, first make sure the sift cable is adujusted correctly as that would cause hard shifting, the next thing is to make sure the fluid is clean and full, i have done bg ****** flushes that have helped but not always, a dirty or bad valve body would cause this and last a bad converter in ****** would do this also. start with fluid level and shift cable adjustment. good day

A problem with the valve body inside the transmission is likely the cause.

SOURCE: Best Spark plugs for a 1993 GMC Jimmy SLE Vortec

AC 41803 Drivetrain:Four Wheel Drive;
@Gap .045" This is a Platinum High Performance Spark PLug


Option : ASP AR25
EngineVIN:W;
@Gap .045"@ High Performance

Stay away from those Gimmick Spark Plugs , they are just more money for nothing. A good platinum spark plug is all you need, the key is to gap it correctly to your application...

On GM products Vin # W it is .045 plug gap
On Gm products Vin # Z it is .035 plug gap

You will not have huge gains in fuel mileage from replacing spark plugs except to say that if your old ones are just extremely bad, there is no magical spark plug with extra mileage manufactured into it.... Hope this helps...

Testimonial: "Thanks for the reply. Spark plugs are pretty basic, but I would have fallen for the higher end. Assume I have VIN W as there is no Z in the vin number"

SOURCE: hard shift from first to second gear

Shift solenoid A is on it's way to failing. Mine did this for a while, later down the road i didnt have 1st or 4th gear at all. When i replaved the solenoid the shifting was perfect.

1993 Suburban 4 speed automatic transmission shifts hard front 1st to second. Transmission is 3 years old, 15,000 miles. It is a factory rebuilt.


That should be the L60-4 truck version
Have the sedan version, 93 Caprice.
That was the first year of the new electronic shifting transmission.
Especialy when cold she will shift hard, but it's normal.
But that depends on what you call normal.
I have gotten used to it over the last 17 years.

Check the tps "trottle positioning sensor, on mine the idle would not stay steady, and shift so hard that it would sound like it was going to break something. it is located on the drivers side of the throttle body with a push in electrical connector.
