My 01 ford ranger started shaking when I put it in reverse or drive?

My 01 ford ranger started shaking when i put it in reverse this morning to get out of my parking lot. It then continued to do it when I put it in drive. I quickly put it in park and shut it off. I turned it back on and waited a minute before putting it back in drive and then it was fine. It has done this a couple times now, what could be causing this?My 01 ford ranger started shaking when I put it in reverse or drive?needs some tune up

oil is too thick

low octane level

those might cause the shake.My 01 ford ranger started shaking when I put it in reverse or drive?Time for Spark plugs most likely. Additional suspects are dirty fuel injector, that is the easiest and cheapest thing to check for, simply dump a bottle of high end fuel injector cleaner at the next two fill ups and run each tank down to below 1/4 before refilling it. If that does not clear it up replace the plugs, and check the wires closely.



Use only the factory specified spark plugs, accept no substitutes!



Always use the factory specified plug in every automotive engine. I can not count the number of times I have traced a drive ability or emission failure to non factory spark plugs. Despite the fact that they are cross referenced to match the application, spark plugs manufactured by any other company are not identical to the factory plugs which are designed from scratch to provide optimum performance for the specific engine involved.My 01 ford ranger started shaking when I put it in reverse or drive?It could be one or more of the following:

check the transmission mount, it might be busted.
