XL2007 Posted September 29, 2007 Share Posted September 29, 2007 So I took my 92 LS400 to the dealer to have the transmission flushed. Service techs looked at the condition of the fluid (about a brownish red - I suspect the fluid hadn't been changed in a looooong time) and said "no way", since according to them the transmission had shed too much "clutch material" for them to do a flush without having to worry about premature failure. They said the thickness of the current fluid was pretty much holding it together. Now if this is so, then wouldn't a "drain and fill" with a bottle of Lucas Transmission Fix hold it together? And how long would I have before I see some serious problems? FWIW, the shifting is getting a bit harsher, especially going into 3rd gear.

XL2007 Posted October 2, 2007 Author Share Posted October 2, 2007 Haven't done anything to it yet. Will talk to an independent tranny shop for a second opinion. Quote Link to comment Share on other sites More sharing options...
SRK Posted October 2, 2007 Share Posted October 2, 2007 I don't know where the myth started that deems "old trans fluid holds it together", but I wish it would die. If the only symptom is a slightly harsh shift performance, get an independant to flush it and see what happens. I wouldn't be in a hurry to pull the trans just because the oil looks dirty. I can assure you the Lexus tech won't rebuild it - their policy is to replace with a factory reman unit. Perhaps he wasn't busy that day.... I think the trans is probably fine. Let us know.
