Rear Diff oil change
#2
Lexus Champion
I had mine in my SC4 done on Tuesday at Integrity Automotive "Lexus Service Center"... They charged $95 bucks for transmission service and rear diff. service with synthetic fluids... Plus they topped off all engine fluids and made a few minor adjustments... 2 great guys(former Lexus mechanics) that love Lexus.
I also had my entire brake fluid exchanged/bleed with synthetic fluid.. And boy was the old fluid dirty! I did that at home with a friend. It took about 1 1/2 hours... we talked and messed around the entire time... As a few guys on this forum said "fresh synthetic or dot4 brake fluid makes a noticeable difference in the brakes..." The power steering fluid is next!

I just changed the tranny oil and rear diff oil on my SC. Use Redline - I swear by this stuff. Smooth smooth shifts now, incredible difference.
For the diff use Redline GL-5 75-90W gear oil. The owners manual says 80-90W but Redline doesn't make that weight, also the 75-90W is fine, it won't hurt anything.
For the 5spd tranny use Redline GL-4 or 5 75-90W MT90. This is different than the diff oil. Do not use the diff oil for the tranny and vise-versa.
There is no way to pour the oil in from a bottle so you need to get a small pump - sold in most parts stores.
Take out the fill plug out then the drain plug out. Clean the drain plug and put back in. Start filling with the pump and stop when the oil starts coming out the fill hole. That's it. It's worth it to do yourself - shops generally overcharge for this procedure.
The diff takes approx 1.42 quarts. The 5spd takes about 2.7 quarts.

SYNTHETIC ATF?
I've been using REDLINE ATF, MTF and oil for years in my Bimmers. I use it in my Rear Diff on my SC4(93), but I was told by my dealer I couldn't use it in my transmission! I had to USE Toyota ATF.
Was he pulling my leg? I'd love to use syn ATF.
Also use synth power steering fluid after replaceing my bad pump!
Thanks!

I guess your leg hurts!!!
The guys at the shop I went to told me to use the Toy-fluid too. I called and check around and the synthetic fluid meets and exceeds the Lexus transmission requirements.
Just call around to several top-notch transmission repair facilities...

Redline in manual tranny
92SC3005SPD great notes, thanks for posting that info. I've been thinking about changing the differential and tranmission oil and using synthetic for some time now.
I keep reading you must use Toy type IV fluid, the problem is the topic keeps hopping between people with automatic and manual trannies. I'm getting the impression that or automatic transmissions, it's best to stick with Toyota type IV and for manual, it doesn't matter so you can move on to synthetic. Can anyone comment on this?

Brake fluid change
Don't have anything specific to Lexus, but it's prety much a universal process... except for Porsches which I understand some have two bleeder screws. The articles below have some good info, when I do my SC300 I'll see if I can't snap a few pix and put together a DIY. Remember, this is a two person job unless you buy a bleeder tool.

FYI: If you've got a manual tranny, there's a slave cylinder with a bleered valve on the tranny. It's the same process to change the clutch fluid.
