The 4L60 and 4L60E use the same transmount and it's in the same exact location, did you mean you changed from a 4L60e (which was standard in 99) to a 4L80e??

something is not right. first off if it came with a 4l60 someone went way beyond a repair or rebuild to get that thing to work. also it was stock with a 4l60e so there should be no issues. any more details?

sorry took so long to reply
99 yukon came with a 4l60 i was trying to put a 4l60e out of a 2000 tahoe in it
for know this won't happen - can make everything bolt up but the torque converter / if i try to get the flex plate to fit the converter the flex plate will not bolt to the crank so thanks for your help but looking for 4l60 now and i did get the cross member in after a little twisting and turning just to have to take it back out

thanks again

if the 2000 was obs then it should have worked just fine. if nbs then flexplate is a different part.
