mjeff87 Posted March 12, 2021 Share Posted March 12, 2021 Preface: I loathe auto trannies, but my KJ has one. 545RFE to be exact. Its in perfect condition but has started to drip (like a dime sized spot about every 3 days or so, not bad but its bugging the hell out of me). I have some leak dye that I've used in the focus engine to pinpoint oil leaks in the crankcase. Could I use it to also trace the leak on my tranny? My mind says it would not matter a single bit if I poured an ounce or so into the pan of the trans, but.....I just want to hear some affirmation from those smarter than me that it won't cause any problems. Its leaking from *somewhere* on the trans body, but its dripping from the lowest point, which i know is not the source. Link to comment Share on other sites More sharing options...
Pete M Posted March 13, 2021 Share Posted March 13, 2021 google seems to imply you're good to go. Link to comment Share on other sites More sharing options...
Minuit Posted March 13, 2021 Share Posted March 13, 2021 I've done it before. I don't see any reason why it would hurt. Link to comment Share on other sites More sharing options...
JMO413 Posted March 13, 2021 Share Posted March 13, 2021 GM and Mopar both have 4 in 1 dye. Engine oil, trans, P/s,& diff if I recall correctly. So you should be good to go. Link to comment Share on other sites More sharing options...
