Default transmission mount question for my 95.

when i drive it on the highway and i slowly increase speed it'* smooth and normal
but now when i mdoing 30-40 mph and want to jump in the fast lane (far left lane) to do 60-70 mph (speed limit 65) i notice it jumps when i increase speed faster..(step on pedal harder). does this mean its a tranny mount or could it be the tranny itself.?

thanks guys give me some good news please...

I would guess that is normal as the trans is down shifting to gain speed. Now if you get an abrupt slam and noise that is another issue.

hello, 88bonnsse there'* a simple procedure for checking for a bad tranny/engine mount.

You need two people, one person in the drivers seat, the other looking in the engine bay looking for abnormal movement of the engine and tranny. Have the person in the drivers seat start the engine and have them put their left foot on the brake firmly. Now have them take their right foot and gently step on the gas pedal momentarily. Do This while shifted in to drive and reverse. This will cause a resistance opposing the engine torque and the engine will want to move. If you have healthy mounts there will be minimal play.

Also when accelerating its normal to feel a slight jerk (a smooth jolt if you will) as the transmission shifts to a lower gear so you can access your engine power. Now if you accelerate in the normal manner and it feels like a big KICK, like someone hit your car with a giant sledge hammer, then it may be a symptom of your transmission not synchronizing things as it should. In a perfect transmission you should feel nothing as you shift gears.

Hope this helps.
