NO. The transmission wiring harness on the 1500 will NOT hook up to the 4L80E transmission and the COMPUTER / ECM will not operate the 4L80E. The 1500 MUST have the 4L60E put in it.
NO. the wireing harness is different for the 4L80E.
It will bolt up but the wireing harness on the 1500 / 1/2 ton will not plug into the 4L80E transmission, there for it won't work. The 4L80E transmissions are for the 3/4 ton trucks and YOURS is a 1/2 ton and it REQUIRES a 4L60E transmission to be put back in it.
That would be the 4L60E. The 4L80E transmissions are in the 3/4 tons.
4L60E in 1/2 ton Trucks. 4L80E in 3/4 ton Trucks.
1/2 tons have a 4L60E 3/4 tons have a 4L80E
4L60E transmission. in all 1/2 tons.3/4 tons have the 4L80E in them.
The 1/2 tons used the 4L60E and the 3/4 tons used the 4L80E transmissions.
That would be the 4L60E automatic transmission. The 3/4 Tons used the 4L80E trans.
4L60E in all the half tons. 4L80E in the 3/4 tons.
If you don't want all kinds of problems, Then YOU should put the 4L80E back in it and be done with it.
4L60E THATS factory for all 1/2 tons 4L80E is factory for all 3/4 tons
That would be the 4L60E transmission. The 3/4 tons used the 4L80E
