248,000 transmission flush

[LoveMyLexus]

So I just had t tech trans flush on my LX470. There is no filter correct only a screen and the pan has a seal so it can or can't be dropped ? Not one issue ever with transmission. Was very dark when replaced. Was this a bad move? I'm feeling that it was the right thing to do but not quite sure. I need to make sure that if I need to have the pan dropped I do it soon. And if there is a screen or filter, cleaned or replaced.

Others will say different, but if it runs okay, and the fluid looks good and is filled to the correct level, then I would leave it alone. It def makes sense to change the fluid at 248,000 miles, but I have heard that old automatic transmissions can lose friction if you mess with them too much. If it runs okay and there are no chunks of metal on the dipstick, then I would just drive it.

IIRC, the 2000 model year had quality control problems with the transmissions, but it only affected about 5%, and the problems had nothing to do with fluid changes. Other than MY 2000 flukes, it would appear that both the A343F and A750F are pretty reliable.

pretty sure there is no filter.

You can drop pan to clean/replaced screen, but do not need to. What brand ATF did you have put in?

Penz. This guy was referred to me by my husband. Called MY mechanic this morning and he said he would have never advised it. He did say to leave it and that usually trans only last about 200,000. Being that I have 248 is really good. He did say that I speeded up the process by having this done. He can get me a trans when I need it and drop it in. Live and learn. Did text my son he said don't do it but it was too late.

I think I would change mechanics if he thinks a LX tranny is only good to 200k. If changing fluid causes a problem,then the problem already existed.

I really like my mechanic. He does good work. I do agree with the statement about causing a problem if the problem was already there. I'm still pretty comfortable about having it done. I'm not gonna stress over it. I love my car and will get it fixed if it comes to that stage. Time will tell.

Another vote for the mechanic does not know what he is talking about. Plenty of member here that has more than 200k on original tranny (including mine) with no problem.

The good news is that you bought a vehicle that was made to last.

This is my last car. My goal is to get it to a million miles haha. I would love to be driving this car in my old age. My husband and oldest son are always trying to get my car. My son has the land cruiser 80 series (he has educated me on a lot of things as well) .

I wouldn't fret either way. The 100 trans seems to be near bulletproof. I'm at 225k with some serious off roading in the last 35k of that mileage. It's still running great.

200k for a transmission to last in a 100 series? No way. Double that to 400k and I might believe it.

If you'd like to get a million miles out of your rig, I suggest you follow the maintenance schedule to the T. Inspect Transmission fluid every 15K is just one of many items. Most local shop don't even know the propeller shaft yokes and spider joint need lubing every 5K or soon depending on use. Don't get me started on wheel & axle bearings & bushing, snap ring etc.

I do a flush every 20 to 30K miles with M1 full synthetic ATF, which is great for my 01. I'll soon be doing a flush on my new 01 LX w/214K, which was done once ~100K miles ago. I prefer M1 and only use full synthetic these days. I DIY my fliud flush so I know what has been done and that a powered flush pump is not used. Some feel that external powered flushing machines' put undue pressure on the transmission internals. This is true of Honda's, not so much the 100's

Here a picture of under maintained propeller shaft slip yoke.

Dry seal and rust, can you here the clunk:

 

[LoveMyLexus]

Yeah wheel axle bearings bushings and such are regularly looked at. Propeller shaft slip yoke information I will look into. Are you asking me if I hear a clunk or making a statement? My car makes no sounds other than the smooth purr. It really does run like a new car. Oil changes are on time with tire rotations alignments and such. When Oil changes are done I ask that they check things over belts fluids any sounds that may be of concern to me. I run only synthetic oil always have.

 

[2001LC]

I was pointing out that most shop's don't go by a LC/LX Toyota maintenance schedule. The slip yoke pic above is from a 100 that reportedly had oil changed every 5K miles. At places like JiffyLub and local shops. Each oil change these need lubing, this one was never done. A mechanic that said trans only last 200k, doesn't know these rigs.

the propeller shaft yokes and spider joint

Would you explain to me where this would be.

 

[offroadminivan]

There are two slip yokes, one on the front drive shaft and one on the rear drive shaft. I assume 2001lc is referring to the u-joints, four total, one on each end of the shafts.

 

[2001LC]

Would you explain to me where this would be.

Propeller shafts (two) AKA drive shafts.

They connect the transfer case with the differentials. Look at undercarriage from just in front of rear tires. You'll see the rear propeller shaft running down the center next to muffler.

Toyota: Propeller shafts (AKA Drive shafts), Drive shaft (AKA front axle, AKA CV joints) spider joint (AKA U-joints)

...and I plan to get well over 200 out of my trans. Not sure how fresh fluid would be bad in a properly operating transmission. Shifting better, worse or indifferent after?

 

[DirtDawg]

To add my $.02, I agree with all the above. Not trying to bash your mechanic, I'm sure he's good, but he clearly doesn't know what he's talking about. Any good toyota mechanic knows that these transmissions last just as long as the vehicle. That being said, I still don't trust my mechanic for half the stuff on my cruiser. General mechanics simply don't know much about the LC/LX platform because it is such a small platform, they will probably only work on one or two in their lifetime. I would suggest finding a mechanic that is more knowledgable on the platform.

As for the trans flush I think your fine. As long as they didn't use a high pressure flush machine you didn't blow out any seals. I would feel better with fresh fluid in there than old fluid. Once again your mechanic advising against this would only confirm my distrust of his opinion. Once again, not saying he's a bad mechanic, just not knowledgable on our vehicles.
