Tranny flush or simple drain and fill???
I've had my 92 LS-L almost two months now, currently have no tranny problems (fingers crossed) and the fluid does not get burnt. I want to change my tranny fluid to be on the safe side as I have no idea when it was last done. I'll be using the Redline Hi-Temp and am wondering if I should simply drain and fill, which I have read will change out about half of it, or should I flush and fill? I have read several threads where those that have flushed, have experienced tranny problems soon afterward, possibly loosening up some gunk or a chunk that clogs something up, leading to failure. Please weigh in......Thanks.

I recommend that you change the external filter if it has not been changed in 30k miles and drian and add your synthetic AFT. You may also want to adjust the transmission brake band.

I think I would just change it a few times. Look at the following link for some information on this.

You asked for it...
and since you mention no history on the transmission I'm guessing you don't know how many miles for sure, yes?
warning, lots of opinions to follow - in fact, too many to point out. Older engines and transmissions switching to a synthetic can cause external and internal leaks - past the seals. Why this is may be attributed to the PAO base stock (Type IV) prevalent in synthetics, i.e., Mobil-1, AMSOIL, etc. PAOs have a strong cleaning ability and are not much good for softening and conditioning the seals. Flushing has the same effect by virtue of cleaning the gunk off the seals & if the seals were marginal to begin with, they then allow leaks past (the gunk was actually acting as an aid to the seal). Using Redline is probably your safest bet in switching to synthetics for an older engine/transmission as Redline uses a higher percentage of ester base stock (Type V) - which does a better job than PAO base stocks as esters do swell seals in addition to cleaning them. For a relatively new transmission and/or engine PAO or ester issue really isn't. If you absolutely feel the need to clean the inside of your engine/transmission look at the sites below for "clean-while-you-drive" products. www.auto-rx.net for transmission flushes www.auto-rx.com for engine flushes |

Thanks for the info....I think I'll change it every two weeks for about 2 months with the Redline Hi-Temp. This sounds like the safe way to go. Is adjusting the bands necessary if I'm not experiencing any slippage? If they are easy to get at and adjust, it sounds like a good idea. If I have to drop the pan and get in there where someone with very little automotive wherewithall doesn't belong, I'm going to stay away from that.
