you say you ran mobil 1 in everything..but be more specific..i assume you just mean you used mobil 1 engine oil? or did you use mobil 1 ATF too? explain further plz. and yes, heard good things about mobil 1 syn for lexus/toyota's

 

I would go the extra mile and do a tranny flush. If your not a DIY'er then the money would be well spent having a dealer or reputable shop do it. I agree to use the T IV fluid unless your burning up the track somewhere. There is a good video I found on here that shows exactly what to do and how to do a complete tranny flush. The guy is working on a Honda, however, the principal is the same. Just remember to NEVER let the fluid get too low when performing this service. Going to do my 95 LS in a couple of weeks. 280K and going strong! I also agree to baseline your car now so you know where you stand and unless your flogging it around the track OEM/equivalent is hard to beat.
