Thanks for the correction and information. Never really ventured into the additives with transmissions. Most of my experience with transmissions comes from Racing and previously 15 years of Demolition Derbying where we abuse the crap out of them. Either the trans is completely roached or rebuilt for the new racing season to prevent the inevitable failure of a power glide.

Very common in Jeeps to see a slipping symptom when the vehicle is cold, once the trans fluid heats up the seals expand due to the heat, Lucas helps revitalize those seals. Axle seals, front seals, pan gaskets, solenoid gaskets, pump seals, they will not be helped by adding Lucas. That being said, it wouldn't hurt anything putting it in there, but I just wanted to clear that up for someone who may get their hopes up.

***Also a note for any DIY'ers, if you are servicing the transmission on a vehicle do not use several types of pan gaskets ie a cork gasket and RTV, I have even seen people use a fiber pack gasket and a cork gasket with RTV in between them. On A604 transmissions we use Cork only. Some people will use RTV only, which is ok if done properly, but choose one or the other. Don't use fiber pack they are junk gaskets that seem to always leak IMO. We have a Wal-Mart down the road from us and they buy the filter kits from Advance Auto and it comes with a fiber pack, and I betcha we fix 2-3 of their services a week.
