The only cars that'll have slippage/limp-mode issues are pre-1997 models. After 1996, the TCM received a flash upgrade that fixed this issue.

BTW- I have a custom one-of-a-kind 3500 stall torque converter for sale. I've been needing to get rid of it, so any resonable offers will be accepted. Cost over $1000 new, it has ~1500 miles on it, and I can let it go for around $400. I'm posting it for sale in the for-sale forum today and if I get no bite by tonight, it's going on ebay. 3500 stall is da shizzle... hangin w/ 5 speeds!
