Planned to get a deep gm 4l60e truck pan but noticed on the web you can get a chrome finned pan w/ drain plug for 700r4/4l60e for like $20, anyone used these with decent results?

 

Bad results here, the chrome is too "slippery" and the
embossed seal feature cut right through a cork pan
gasket. Nothing but sealing troubles for me.

Truck pans are similarly cheap but better in my book.

Fins on the bottom won't do much for you. Not any
kind of substitute for a real trans cooler.

 

If the pan is stamped 700R4 and they are telling you it will fit a 4L60E, don't believe them. It will bolt right up, but there is a hole along the edge of your transmission case where it mates up to the pan. The 4L60E pan has a relief in the edge to clear that hole, the 700R4 doesn't. I don't know the purpose of that hole, but it appears to drain oil down into the pan from up in the tranny. Without that relief, that hole is covered by the edge of the pan. I bought one of those pans trying to cure a leak in mine and it got much worse with the 700R4 pan. I think oil from that hole was trying to come out into the pan and ended up seeping through the gasket and out the edge, but that is just a guess on my part. The pans actually made for 4L60E all seemed to be more expensive. I put the original pan back on and the leak got better.

 

Really? Hhmmm...could be a lot of other pans out there just like it then. Something to look out for.

 

A lot of vendors say they are the same, here is just one example http://racetransmissions.com/store/p...roducts_id/152
