When I accelerate "easily" from a stop, my car shifts fine-both up and down. If I need to enter traffic, and accelerate a bit more, it shakes briefly, then continues fine. Could this be the onset of a serious trans. issue? I have sentimental reasons for keeping and replacing most every external running gear part on it. I have even had the block, and head tested with a good report. I got the car with 80,000 miles, it now has 105,000. If I have to park it, I will. However I have put far too much $ into this car to ever sell it.
The acceleration problem may be related to air/fuel settings rather than transmissions so work on the injectors/fuel pressure / carby settings first
Testimonial: "Indeed the injectors were one of the issues. The other was a lower mount. I said I would never sell that car, and I was wrong. I bought a new van, and a close friend needed it the same way I did, so I sold it to him. It was in excellent running condition, and even had the sporty looking AWD bumpers, and wheels put on it. Thank you so much!"
SOURCE: shakes side2side under acceleration at 38-48 mpn only
had exact same problem and had a drive shaft (????) extension replaced. This item moves in and out when the engine rotates under torque. If not able to move correctly you get this vibration. Only needed to replace the one on the driver's side - other side okay, but it was maddening that you could get the car to vibrate at 35 to 45 mph but at no other speed.

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.

May not but stranger things have happened & for the price of fluid, I feel bad if I didn't try that first.
SOURCE: Trans shifts very hard after 5 minutes of stop and go traffic
A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.
Some possibilties, not all!
