Hi just found this site looks cool with alot of good info! Was wondering if the tranny fluid and filter have never been changed at 92,000 should it be done right away. I've heard that disturbing the fluid and filter may damage the transmission. 89 firebird2.8 Thanks

 

change it, always good to do

 

What can happen is if the trans fluidhas been in theree so long *AND* the tranny is showing signs of slippage, you do not want to change the fluid or it will immediately kill the trans useage.

HOW and Why?

When a high milage trans starts to slip, the old fluid retains some of the friction particles in the old fluid that will help aid the internal clutch packs from slipping. When you drain the old fluid and install new fluid, the clutches will really slip and the tranny is dead.

If you are not showing any signs of slippage, then service it immediately. Otherwise, leave it and start saving your money for a new trans real soon.

 

wow didnt know that... ill keep that in mind.

 

wha?
well what you said makes sence but.... ive noticed from expiriance that if i have a tranny slippin if i change the filter and fluied the sliping tep goes away.,for a while.,.,this was an ol trick i saw my father do when selling a ride with bad trans.,.,it has worked for us befor., but once it starts slippin with the new fluied its GONE

 

does any of this apply to manual trannys?
