Transmission Fluid Really Dirty, Replace Or No?

[GFunkError]

I went in for a tranmission flush and fill and my mechanic advised me against it. He said the fluid had been in there so long that it had residue in it. He felt that if we put new fluid in there, it might break the transmission. So he just took the fluid out, took out the residue and put it back in. What do u guys say? How much would a used transmission cost?

Well if it is operating ok I would try to salvage it. Nothing to lose. Two years ago, I was having slipping problems and figured a rebuild was on the horizon. I put my tranny on one of those circulators and had the BG treatment done on it. It fixed the problem and I have had no problems since. The guy said that it was filthy. I've heard that kicking some of this sh*t loose can cause problems, but if they drop the pan and clean out the debris really well, this can be beneficial. The BG worked for me.

What is a BG treatment. I have always flushed and adde amsoil in my oyher cars. I have never heard of keeping old fluid.

Only in the 70's on some domestics was it better to keep the old fluid rather than replace it.

It is always a good idea to change it when it needs it and especially if it is really bad.

If your mechanic is not a Toyota / Lexus specialist, then he likely doesn't know much about Toyptas recommended procedures for servicing Toyota transmissions. The proper servicing procedure on an old, neglected Toyota automatic like yours is to drain and remove the transmission oil pan, clean the pan and magnets in the pan with a brake cleaner type solvent then remove and clean the transmission oil filter with brake cleaner.

Reinstall the filter and pan and add fresh Toyota Type T-IV fluid, available in 1 quart bottles form Toyota dealers for about $3.80 a quart. Add as much fresh fluid as was drainsed (about 2.1 quarts).

Drive the car for a few days then drain and refill the pan again (but don't remove the pan)

Repeat this procedure 4-5 more times over a period of several days or weeks so the old fluid and residue is gently and safely cleaned away and the transmission WILL survive and shift better.

New transmission fluid is an excellent metal cleaner and that's why it will gently and safely cleans up your transmission. No additional cleaners like the gimmicky BG products are needed.

The BG company loans auto service shops use of their lube flushing machines if the shops

agree to use BG branded lubes and cleaners. The shops nearly always agree to theis arrangement because they can make big bucks selling the concept of "flushing" mechanical components to the public. So if you prefer to help your local auto repair shop owner make payments on his vacation home, then buy all the BG flushing servives he offers.

Werd. And there is a big difference between just changing the fluid in the system and the whole resevoir.

Interesting, it may be my transmission oil leaking and not my engine oil after reading that entry. I can't see were its coming from, but underneath what looks like the engine oil pan is were it drips ONLY when the engine is warm and quite slowly. If it is engine oil, I have no idea what kind of oil was put in there, put I do believe it was 5w-30, not sure what brand. I'm going to get it checked out probably this weekend hopefully, and I hope its not the rear main seals. If it happens to be the transmission in the other hand, I think I have much better options in this case.
