2002 LS430 base model. 100k. Bought new and dealer serviced every 5k. Garaged, well maintained. Appears to have developed a slight ooze from the front of the transmission pan gasket. Have gotten a tad miffed at my local Lexus service dept, so am having a certified Lexus mechanic fix this problem. For my general information, what besides the gasket and fluid replacement need doing? Filter, etc. Helpful hints, no-no's, etc would be appreciated.

Am not real familiar with the Lexus and Toyota and other recent transmissions. The last tranny I rebuilt was a 1953 Packard Ultramatic, but have serviced my own 454 GMC, 3800 Buick, and several manual VW's dating back to a 1959 beetle. So any comments would be appreciated. And will post on the Lexus Owners Forum also.

Thanks,
****

 

When I change the fluid I do it through the trans fluid cooling line that attaches to the radiator. There is a tutorial on here somewhere. You will get 3-4 quarts if you drain the pan. If you pump it out by disconnecting the trans cooler line you can change it all. Obviusly much better service and you only pay for the extra quarts of fluid. Definitely a DIY.
