How often are you refreshing your transmission? I've had my FLT 4l80e for over 2 years since last refresh and was wondering if I should go ahead and send it off even though it works flawlessly and doesn't overheat.

 

If it aint broke dont fix it

 

X2. As long as you change the fluid and filter regularly, nothing to worry about imo.

 

Good to hear the 80 I built you is still running strong. I would say as long as its working well then it should be fine. It is an 80 you know! As mentioned I would service it and do a visual inspection of the pan when you have it down. As long as it looks good and there are very little signs of debris I would say run it. If you have any other questions just ask. Vince

 

Thanks for the response. I feel alot better about it now.

 

When to refresh? How about when the 3-4 shift is at 35 like mine?
