can anyone tell me by looking at the numbers if i have 4l60 or 6l80 or even 8l90 transmission. according to engines computer i have 2016 GM1500 engine. don't know what exact car it came out off. i think its 6l80e tranny , but got know how to clarify that . also is 4l60 dipstick the same as it is for 6l80? i heard hole is different size , true?? thanks in advance
That is a 6L80 transmission and as for the dipstick it is $30 on ebay, I believe they are different dipsticks between the 4L60 and 6L80 so just to be safe buy the OEM Dipstick.

Dockrocket1967 .
thank you for the response. for curiosity reason, how do you know the difference between 6l80 vs 6l90 .
For the record, whom might need this info for future: 4l60 dipstick hole size is different than 6l80/ 6l90 trannys. So they are NOT the same
I know of some of the internal differences between the two but external differences are not much. I know there is a difference in pans but also the 6l90 is a little bigger...here is a dimension chart
Also I need to revise my previous post. After doing a little more search on the numbers of the transmission it shows the transmission being behind a 4.3L which would be a 6L80. If it was for sure in a 1500 then that would be correct. The 24270744 Number is a 6L80 part number the 4CEA designates both transmissions available I guess
