Transmission Pan Stripped
Just got the car last week. 99 gs300 with 200k. Wanted to do a drain and fill instead of machine flush because of the mileage and unknown history. My bolt just spins either direction. I can get it to the point where it is tight and doesn't leak. my fluid is dark. i need it changed
is replacing the pan and filter my only option and how will my tranny react to this huge change at this point its running smooth now.

If you don't want to get a full tranny flush because due to fear of the high mileage, I'd recommend at least flushing out the old fluid a few times on 15k interval. Just to try and get all the old gunk out as much as possible. Idk why a full tranny flush would be bad at any mileage. But if what your were told is that it's bad, do it the safe proof way. But still treat the car good you know. Hope your troubles are resolved bro.

The reason a full flush is a bad idea on a high-mileage car is it can cause the tranny seals to leak. Over time, especially if the tranny hasn't been maintained properly, particulates build-up in the spaces left when the seals shrink with age. If you flush these particulates out, then the seals will leak. However, if you do one or more drain and fills, then you are a lot less likely to cause a high- mileage tranny to leak.

They quoted you right on the parts. I paid the same down here in Florida for my atf iv

When I went to do a trans drain / refill I found out my trans drain bolt was stripped by previous owner. Long story short - I ended up replacing the trans pan, I believe it was around $150 shipped from sewell (much cheaper than local dealer).

Just for future reference, the easiest way to drain the tranny is thru the cooling lines going to the radiator. Loosen the line on the driver side, crank (but don't start) the car until it pumps out the desired amount of fluid. This way you don't have to worry about the tranny drain bolt at all.

hey did you do the filter in there as well or just the pan. while its down i was thinking about the filter.
#12
And the filter you are asking about. Yea take it out. It's a mesh screen, clean it, and just put it back in, as well as all the magnets, clean those off as well. Like mentioned yea you also have to replace the crush washer for the Trans plug. (Bolt were talking about) I can't recall the specs of how many lbs to torque to so unless I can find it, I'd hate to tell you wrong and it happen to you. I'll try lookin I'm sure it's in the sticky for "DIY Trans flush though." Where all.... Your questions answers, ultimately lye.... Hence it's name, "Ultimate sticky.." Haha. Cheers.

Yes absolutely correct about the bolt though - don't over tighten!
Purchased - Pan, plug, crush washer, FIPG red (gasket), fluid.

Yea if the threads did indeed strip, ehh... I'd probably just get a new pan for peace of mind, even know tapping is 100% legit. Done. It a trillion times, but if it's minimal material left to work with, yea no thanks, I'd rather know I'm going to make it to Vegas and have my money to gamble then to take the gamble with losing my oil and Trans on the way out there, LOLOL!! Probability of winning either may be just about equal, F THAT! HAHAHAHA. Glad it worked out.

Once out, I tapped new threads and got a new bolt. Remember to check the length of the new bolt. It has been 5 yrs and many miles and every thing is fine. I have been looking for a replacement pan but the price does not justify replacement.
