Transmission shudder My 1993 Honda accord anniversary edition transmission "shudders" when I start accelerating at any speed i.e. freeway stop and go traffic, then runs smoothly. If I accelerate rapidly the "shuddering" does not occur. Sometimes the D4 light flashes and the car will not go at all. If I turn the engine off and then restart, the D4 light goes out and the car runs again but still has the slight "shudder" upon acceleration. A couple of times the car would not start after I stopped for a few minutes unless I let the car set for approx. 20 or 30 minutes. Is this the same problem? I had the transmission fluid changed about 10,000 miles ago. I would really appreciate your help.

Question edited for clarity, Lubegard and Shudder, not 'shutter'.

Yes you can.

• Transmission Instant Shudder Fixx is a concentrated friction modifier formulated for eliminating torque converter shudder problems - instantly
• Works with any automatic transmission fluid except Ford Type F and CVT applications

is this an extended cab ,4wd,automatic or manual transmission ,,studdering can be anything from needing a tune up --tires balanced -motor mount-suspension- c/v axle --u-joints torque converter-rear -transmission clutch-4wd components etc

I would start with fuel filter.

Ckeck your govenator .

You need to find out which system is causing it first. Lift it and run it like that, get some help and find the source of the shudder

buy shudder fix might need to get it from a transmission shop its the torque converter lockup causeing the shudder

smell the transmission fluid and see if it smells burnt, If so the tranny may need rebuilding.
Check the level while your there. To prolong life of car don't make it do that.

it sounds like you have worn engine or transmission mounts. if it was friction from the transmission it would happen anytime you accelerate, not just from a stop. place rubber or wood stops in front and behind the front wheels, pull the e-brake. now have someone hold the brake pedal and start the car. have them put the car in gear and rev the engine, making sure the car doesnt move. while revving the engine, look at the position of the engine and how much it shifts around from its initial position. excessive movement of the engine indicates a worn or loose mount. this will also affect acceleration from a stop. what you are experiencing is the weight of the car catching up with movement of the engine. once they come together, the shuddering stops.

That s light is an indication some is going out in your transmission check your transmission fluid level engine off,if ok smell fluid see if like burnt
