Thumbs down Toyota ATF the best

My buddy sells it and swears it rivals Toyota ATF as well as Mobil 1 Syn engine oil. I read the literature and although it is compelling I would stay away due to the replacement cost of the tranny and only use Toyota ATF.

Default ATF - Drain and Fill

I just bought a 93LS for my daily driver earlier this week and found several posts about the tranny shutter and the cure in which people have changed to type IV Toyota Fluid. The owner had all the maintenance done over the years but I am assuming that they places he got it done put the Type II atf fluid in cause thats what the books say as well as all over the dipstick.

Anyways....I did a drain and fill last night and got about 3.8 quarts out. Is that about right???

Also, is it OK to mix the Type IV I put in with the Type II that I am assuming was in there??? It made a pretty good difference regarding the shutter and was a lot smoother at the 65-75 mph mark. Whats your thoughts???

type IV fluid replaced type II completely in the late 90s. since then dealerships have ONLY been putting in type IV on all trannies requiring TYPEII.

I'm pretty sure it's been awhile since this guy has done any service (fluid changes) for the tranny. I'm also pretty sure that he probably didn't have the dealer do the service. Would a shop put in Type II if it was serviced a few years back???

Would it be ok if Type IV was mixed with Type II???

Yes, its perfectly fine. Just make sure you only use T-IV fluid in it. 3.8q's sounds like a whole lot. Should have been about 2 for the LS

Anyhow, just use the dipstick to make sure you dont under, or over fill.

I thought 3.8 was alot as well from reading past posts. I measured all the fluid that was in the pan/container to make sure I put in what i took out. Wierd huh????

I may do this a couple more times and be done with it. I noticed a big difference just doing what I did last night.....so 2 more times should be perfect.

Yes, i've noticed an improvment in the transmission after a drain and refill. Really noticed it in a friends 96, that wasnt serviced well in the dealer prior to the purchase. It was almost night and day. Make sure you drive a good amount in between to mix the fluid. Somethign along the lines of 50+ Miles.

That quote makes me so happy I definitely need to do this a couple times on my LS. I'll do it after I replace my lower ball joints. Man, learning to do all these things is so rewarding. You get to know your car better than you thought you could, and you save so much money becuase you're knocking off most of the things on a dealer's service list.

Tranny Studder can be caused by the ECT program which shuts off the spark to the engine for a split sec . Make sure your plugs are good, new and in proper order. My tranny shudder dissapeared when I changed the plug gap to the proper size. If you took out 3.0q of liquid from your tranny it was over filled. If you put in 3.8 you overfilled it again. Check by using dipstick when tranny is hot 10 miles of driving.

I'm a newbie with 3 months under my belt in a 1999. Do these torque converters have drains so as to get more old fluid out? My '89 MB 420 SEL works this way, takes around 8 quarts.

I just flushed my tranny yesterday with a machine. They used 13 liters of fluid to make a complete flush of any residual. The 2000 LS manual shows 8.4L or 8.9 quarts for a dry fill and 2L or 2qts for a drain and fill.
My tranny is now much smoother but i do not have the more crisper shifting i was used to anymore even in PWR mode.
