cjmatt · Apr 22, 2004

I wouldn't think it would hurt it.. only a quart.

please don't flush it..

just drain it and and add back in what comes out.

Does your tranny leak?

cjmatt · Apr 22, 2004

yeah its leaking at the connector where it goes into the radiator. its been leaking ever since ive had it and i figured today would be a good time to add some. what detrimental effect would the quart or so of different fluid make. has anyone else had this leak and how can i fix it?

Tighten the fitting if its leaking at the radiator, if the line itself is leaking replace it.

I am new here, so maybe I am missing something, but what kind of transmission does it have? The fluid to use depends on which tranny is in there. According to my full-service manual for 2000 XJ's if you have an AW-4 Automatic transmission, then you are supposed to use ATF+3. The only warnings i have seen are for using Dexron II in a transmission that calls for ATF+3, and that is because it will produce "clutch chatter", but like I said, I may be missing something here.

ive got an 89 limited and the AW-4 but the trans is out of a different year and supposedly has 90k on it so i doubt its as old as 89. i read that it called for dexron III and my haynes says mercon. i used atf+3 cuz its what i had laying around and they said its for chryslers. can anyone tell me what they are supposed to have

I am pretty sure that if its an AW-4, you should be using Dexron II E / Mercon, however I do not know about all years of the AW-4.

Funny, cuz I have the exact same manual and mine says the AW-4 uses Dexron II E / Mercon. The 30-RH is the one that calls for Mopar ATF+3 Type 7176, and says that Dexron II is not recommended due to clutch chatter.

You are exactly right, my mistake. I typed it out back-asswards.

Don't worry about it- on my daughter's 1990 with AW4 automatic transmission, it's been running about 1/3 of the fluid ATF+3 and 2/3 Dexron. The manual calls for Dexron. The mechanic who checked the transmission when she bought it a year ago puts ATF+3 in, and claims its better tranny fluid. I don't recommend straying from the manufacturer's recommendations, but there has been absolutely no ill effect from running this mix, so far. 4xBob
