LS Almost Stalls When Coming to a Stop?
#16
finally got some time to work on the car today. Drained the fluid, dropped the pan, replaced the filter. I also checked for any loose wires and tested the ohms on the solenoids. All were around 10.5 and 11.5 ohms. (Battery was disconnected). I also bent the connectors a little to make sure there was a good contact. Some of the guys on the GS forums were having some luck with that. Fluid was bad and filter was definitely due for a change. There was NO debris at all on the magnets.
Once back together and testing results, my harsh engagements into reverse or drive from park were no longer happening. Jerking into gear on up shifts were no more. BUT STILL... When coming to a stop car wants to shutter on the last 20mph. It's like it doesn't want to come out of 4th or 3rd. There are no codes, (for now) but I'm sure it will pop back up after driving around some more. I'm probably have a full diagnostic done on the trans. Perhaps get the caps done.
Any thoughts? I've been reading all over the forums. Most stories end at the drain and filter change.

97 LS400 with 200k just do not tend to have transmission issues, at all (at least not any that a fluid and filter change won't cure!)
being in Florida and being a 97, this sounds like a textbook case of failing ECU capacitors

What's the significance of the car being from Florida - heat, humidity or both? Coming from the north of England not problems I am familiar with! [I knew I'd find a benefit of living in a cold climate if I waited long enough]. Seriously though, are cars from a cool climate less likely to suffer from capacitor problems?

we don't fully understand it, but hot and humid Florida has ECU capacitor issues reported at a higher rate than any other place, although locations around the world are affected, just not at such an extremely high rate.

also cars that have sat for extended periods, this is also very hard on ECU caps, capacitors are like tiny batteries, and we know that batteries that sit for a long time without being used tend to go bad fast. - This is why any ECU from a junkyard or ebay should have its caps replaced ASAP.
