Ls3 and 4l60 So the oil pump went out on my 98 z28 while doing a run and killed my engine. I will be swapping in an ls3 and can it while I'm at it. My question is how long will the 4l60 hold?

We just had a similar thread with a poll:

Besides the engine's power level, other factors are the mileage on the trans and whether you have street tires or drag radials/slicks. Street tires tend to be the weakest link, but with drag tires the trans tends to be weakest link.

One poster mentioned RPM transmissions. You might want to give them a call. They can advise you on core and cost of modification. Also bell housing has to be the right one too.
Question is really compatibility of a 4L60 and LS3 ECM requirements. You might want to do some serious research on that. Wouldn't want to have to pull it and replace it and or have it gone back into to be modified to work.

Best advice I can give you is to address issue with one of the major transmission shops that advertise on this site. I found about bell housing problem back in 2010 when building one of my cars.
Didn't find out about the internal provisions needed for ECM until trans was in car and this was a 4L65E. 4l60 would not be my choice to go behind an LS3. Late model 4L65E or better yet 4L70E.

Yes there are compatibility issues.
LS3 engines have 58x reluctors and therefore cannot directly be run from a LS1 PCM. (Unless you use a 58x->24x converter box.)
Late model 2006+ ECM/TCM will work with a 4L60E but only if it has ISS (Input Speed Sensor) which was introduces in 2006. The ISS cannot be disabled.
Sorry I don't know if there is a 58x PCM/ECU/TCM which does not require ISS.
And 58x ECU are also drive-by-wire using an electronic throttle.
Therefore, IMHO, the best way to run an LS3 in a Gen 4 would be with the 58x->24x converter box. The Lingenfelter TRG-002 58x-24x also converts the LS3 4x cam signal to the LS1 1x cam signal.
All LS-style 4L60E have the same bell housing. The LS-style (300mm input shaft) 4L60E was introducted in '98.
