Currently my vehicle has been in service for 120,000 mile service for a major serpentine belt replacement. Also all hoses and new fluids have been added. Bu at stop lights it can run really rough and starts shaking not to mention stop signs. Do you think my car needs a new Transmission? If so how much time will it take installing it and rebuilding the engine.
How about the price tag?
Thanks,
Glnn

does it do that in park or neutral? if it does, speed the idle up slightly, should fix the problem, i think its an inline 4, so they run rough anyways, dont expect it to run smoothe, if it is the v6 then it still is probably the idle in which case it should be signifigantly improved after adjustments. i think the new belt is either allowing the engine to run faster or slower than before, causing the uneasy idle

Hello there, I have been a toyota tech for 18 years. 120,000 miles is nothing for this car if you have taken reasonbly good care of it you shouldn't need a rebuild for a while. First off it sounds like you have a problem with your spark plug wires. The plug wires run down the center of the valve cover through a tube and over time the material breaks dowm and the spark wants to jump to the side of the metal tube instead of through the spark plug. I would recommend replacing the plug wires. The wires come with the distributor cap, replace the rotor and plugs and you should be just fine. Good luck!

That doesnot sound like a Transmission problem. your engine is having a hard time running on low rpms.
Get your car to a good well known mechanic. some times, small problems like maybe the belt u renewed, could cause problems.
My 98 corolla engine shakes a bit on slightly higher RPM than idle which seems normal for corolla
Emm.... American Cars are not always reliable. You may got this one make and model that is reliable but majority of American cars are filled with problems for an average comuter. my Buick doesn't give me any problems because I take good care of it. an Average commuter wouldn't. So please stop braging that everywhere Daniel.

If it runs down the road fine, but idles like poo, then more than likely there is a vacuum line at the intake manifold that has come off, or is not connected propperly.
Your engine is sucking plain air and causing too lean of a condition in one or more cylinders causing a missfire.
At idle with the hood up, look and listen for a high pitched whisleing or sucking noise where a small hose is not hooked up to the intake.

Did you do the work on the car? If not take it back to who you had do the work and let them know it's running poorly. You never mentioned if you have had the plugs and wires replaced. If not I would look at a good tune up on it. Replaceing the fuel filter, plugs, wires, and if needed the airfilter, PCV Valve, and an injector cleaning. this should take care of the problem. Also if you had the timing belt replaced and then noticed this problem it's possible they have the belt 1 tooth off.

it sounds like the torque converter but those are only on automatic transmissions so if you have a manual please ignore this answer. my AMERICAN car has over 310,000 miles on it with ZERO drive train repairs......so buy American next time
