transmisson problem
Was driving my car tonite and the tranny started acting funny. Like the torque convertor was locking and unlocking very rapidly. Also at one point I pushed gas rather hard and it feel like it was slipping and then started to shudder. This happened about 35-40mph. Took it out on the road and it did the same. Shut the car down and checked the fluid and everything is ok. Nothing burnt and fluid is bright red. Let the car sit for about 2 hrs. and now everything seems to be fine. I wish I had more time to check it out but I'm leaving on a trip for South Dakota tommorrow.

A way to test of a failing Torque Converter is simple. If it starts to shudder again with one foot, maintain that speed, with the other foot, apply the brakes GENTLY just enough to add some resistance to the moving car, remember, you must maintain your speed, so constant foot feed is needed. Does the shudder go away? Generally, If it goes away, you DO have a TCC issue.

it could be as simple as a plug wire. drive toward an incline at 45-50mph on cruise. does it stutter as you start up the incline. replace #6 wire and check #6 plug and try again. it would be best to replace all wires.

Not sure what the problem is.... But these Converters are designed to be able to be locked at a low road speed.... I believe that they use a Graphite woven clutch.... this clutch will take the abuse of varying amounts of slip at the low road speeds...
sounds almost like an apply issue... But at the Same time it may be good to look at the TCC slip rpms under full lock or 100% apply...
also at the same time has the fluid ever been changed? And how is 4th gear?

Don makes a very good point. Never thought of it until now, could be as simple as an apply issue in other words, poor line pressure. Most Transmission shops will attach a scanner to it and read the values for you, and give you at the least an idea.

The car drove fine all the way on my trip. The shifts are fine, the tranny color is a bright red and I'm not sure of when the fluid has been changed last. It'* on my list of things to do. Overdrive is fine as are all the other gears.

Back when I first got my 93 I had a problem similar to yours. Mine turned out to be a completely wrong injector. There have also been other posts that talk about the same shuddering and it turns out to be ignition related. I would not rule out the ignition as it will for sure show up when your lockup kicks in. Thats when mine was acting funny. Everytime the lockup kicked in the car would buck like crazy and I originally thought the supposedly rebuilt tranny was junk. The people on here proved me to be completely wrong. I am grateful for that. I would check the plugs, wires, and coilpacks to make sure it'* not them causing the shudder.
