rebranger Posted April 27, 2019 Report Share Posted April 27, 2019 I have a 1999 Seville, a cream puff with only 67K miles. Cruising down the Interstate @ 70 mph, she begins to rev a bit, no warning lights, nothing. I pull into gas station & stop for gas, she won't pull away from the pumps!! Let her cool a bit & finally she moved out of the way. Made a clunkiing grinding noise. Full of fluid, nice & red & no burnt smell. I called several tranny shops in the area & NOBODY would touch my 4T80E! Checked the on board puter & no codes. Got my scanner & no codes. Towed it home & removed tranny, tore it down, solenoisootds good, TC good, bottom pan & filter full of black molten soot! Metal filings on screens of other 2 filters. Continued tear down,, PLANETARY GEARS STRIPPED, no teeth!. Anybody ever heard of this on the 4T80E? First one I have ever seen & I have rebuilt about one a year since they came out!

BodybyFisher Posted April 28, 2019 Report Share Posted April 28, 2019 I have never heard of this happening very odd. Did it look like this?

rockfangd Posted April 28, 2019 Report Share Posted April 28, 2019 I remember those. They were fine when cold but banged when hot. And eventually had nothing left. Sungear, cookie gear, multiple names. Not really heard of the issue on the 4t80E though Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
