whh333 Posted February 20, 2004 Share Posted February 20, 2004 I got a Haynes manual for the Camry, which covers the engine in my Lexus ES300 and it specifies that the differential is isolated from the transmission and to fill it through the fill plug. After draining the transmission fluid and differential fluid, I kept pouring more that the 1.9 quarts it specified through the plug and the fluid level started showing on my automatic transmission dipstick. I looked in the past posts and they state the 1998 models have a combined reservoir for the transmission. Is this the case on the 1995? How do I fill it? I finally poured in a few quarts through the plug, then topped up the transmission through the transmission dipstick tube. Could I have just used the transmission dipstick tube for all of the filling? Also, I was buying parts at my Lexus dealer and casually stated that I would just use Dextron II or III to fill the transmission after dropping the pan and cleaning the filter. They gasped in shock and made it sound like a sin against nature to use anything other than the Toyota transmission fluid, Toyota IV or something like that. I bought the 6 quarts of the Toyota fluid to do the right thing, but my Lexus owner's manual says to use Dextron II and the automatic transmission dipstick says to use Dextron II. Other than the fact that the Toyota IV fluid is $5.00/ quart and Sam's sells Dextron III for $1.00/quart, is there any difference that matters? Thanks for any ideas.

dropspace Posted February 20, 2004 Share Posted February 20, 2004 i had my 92 flushed awile back with dexIII and the diff filled with the same stuff. it's not a problem to use dexIII as far as I can tell. It wouldn't be the first time a dealer tried to convince you that there is no option but theirs... Quote Link to comment Share on other sites More sharing options...
SKperformance Posted February 21, 2004 Share Posted February 21, 2004 dex 3 is newer but the same the diff needs to be moved and the fluid heated to get the fluid to move into that section which is why it didn;t flow out but it is the same fill point.

whh333 Posted February 24, 2004 Author Share Posted February 24, 2004 Many thanks for the replies. The engine heat an flow of oil into the differential must be the reason I thought I had it all full, but two days later I was showing low fluid even though there were no leaks. I filled it again when hot, thought I had it full again, but the level would drop again. Finally got a stable reading. Thanks again.

lexis lexus Posted August 26, 2011 Share Posted August 26, 2011 I believe its a separate fill plug for the dif, run a funnel/hose from up top after taking the plug out. LL Quote Link to comment Share on other sites More sharing options...
