Question about 2005 Toyota Tacoma
It only happens while in Drive and when I get to 25-35 mph. Once I pass those speeds, it's fine. Mechanic thinks it is the transmission, but I am seeing different posts online about it being rear transmission mount + U-Joints. It doesn't happen while in any other gears. Looking for any information possible. 2005 Tacoma automatic double cab, not lifted - 150k miles. Thank you.
Assuming it is 2 wheel drive; find a smooth quiet street slightly downhill wouldn't hurt, get it to the speed it vibrates and put it into neutral (be careful not top hit reverse while doing this). If it still vibrates then it isn't likely to be the transmission.
Second test would be to chock the front wheels, jack up the back wheels and put quality jack stands under the back axle. then try running it with the wheels off the ground using the parking brake for drag. This will allow a friend to walk around the vehicle and try to isolate the vibration location and at the same time you can observe the back tires and wheels to see if they are not running true. If it won't vibrate with the back wheels up and some drag on the brake, suspect the front wheels or perhaps the rear axle bearings (which won't have any weight on them).
Third, with the truck off, in neutral, jacked up and jack stands securely placed, try manually twisting and wiggling the U-joints. You shouldn't feel any play and they shouldn't make any clicking or grinding noises as they are rotated. Also turn the drive-shaft by hand and look for any dings or bends. Then try wiggling the rear wheels top and bottom; in and out as well as rotating them by hand, you shouldn't feel any play.
Fourth, look at the inside of the rear brake back plates for any oil or brake fluid leakage. fluid in drum brakes can cause all sorts of weird and hard to locate vibrations. You may want to take the opportunity to pull off the rear brake drums and check out the brake wear while it is jacked up.

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.
