YesHey Nick,
Is there any way to tell a 4L65/4L70 without taking it apart?

Id tag 1KDZ to 6KDZ = 4L65E. If the tag is missing or unreadable, look on the under side of the case by the ext housing - ot will be laser-engraved there. Ill edit this post with the code for the 4L70E in a bit.Care to elaborate?
Hey Nick,For anyone that's curious, I did a video tear down of a 4L65E where I talk through the part differences between it (and the 4L70) vs the base 4L60E

There are aftermarket 5-pinion planetaries but I would not recommend using them...I only use OEM GM and acquire them via my local hard parts supplier or directly from a 4L65/4L70 core. I rebuilt a trans once with an aftermarket 5 pinion set and the rear planet came apart after about 2000 miles or so...trans had to come back for re-work / planet replacement...No issues with the install/fill and no lube restrictions in that system...Planet just failed. Replaced with an OEM planet and never heard from the customer again...This was about 8 years ago...Hey Nick,
Are there knockoffs of the 5 pinion planetaries? I've found some on evilbay with pretty low prices. Are they any good?
