Transmission Worries When first started the transmission works fine can make holes in yard. After running for about 10 mins. the transmission doesn't shift.

Speedometer will not make transmission act up. Check the fluid level and depending on mileage you may have to replace it.

might be that you accidentally disconnected the crank sensor close to the transmission, this gives a no start condition without a check engine light on most cars...

Check the oil level in the transmission for one. run a fault code check as well

You don't have a clutch in that automatic, check your transmission fluid first. Make sure you run your truck for 10 min. or so before you check the fluid level. If your fluid is correct then take it to a mechanic, they can check your transmission with their computer and see exactly what is happening when it can't find 4th gear.

ANY SAAB PROBLEMS WILL HAVE TO GO THROUGH THE TECH2
FIRST BEFORE ANYTHING CAN BE SAID.IF THAT DOESN'T FIND ANY PROBLEMS THEN YOU HAVE TO DIG DEEPER

look for a vacumn pipe from the manifold to the gearbox ,this vacumn pipe makes it change gear

The front pump has went out on your transmission and for the model of your car it will cost you from $1500 to $2400 to get it fixed

I would start by checking the fluid level. THis is most likely a 700 r4 Overdrive transmission, The dipstick is located at the back of the engine bay on the passenger side. The vehicle needs to be running in order to check trans fluid. Pull the stick, wipe it and put it back in the tube, then quickly pull it again, if you don't see any fluid on the stick you are at least 2 quarts low. If the transmission fluid id dark black and smells bad, then your clutches inside are probably toast. That's where I'd start.

It has fluid. How much though? The vehicle should be running, warm, and in park. Then check the transmission fluid if it is fine after checking I'd start takin it to the transmission shop, or the junk yard.

You may have a problem with the contacts in the ignition switch (not key part), when you crank the engine a signal is sent to the fuel pump to run, when it starts and you let off the key another set of contacts keeps the pump getting power Through a relay), these are known as crank and run modes.
