what years?

ok my burb is a 95 and a buddy has a k3500 that's a 93 that had a 6.5 in it from the factory has a gas 350 in it now and is parting it out......will the 93 4l80e work in the burb?......

95 was a year that the trans went to an upgrade i believe but it might have been 96. look at the harness on the trans. if it is the same as yours then it will swap with no changes. if there is a diff plug, there will be no mistaking the diff, you can get a diff harness from http://www.electricaladvantage.net/4l80esolenoidmasterkitwinternalharness.aspx and then it will work.

Make sure to use the diesel tq converter

we left the diesel converter in it when we put the gas engine in....

No, the 1993 is a redhead stepchild. The TCC solenoid uses a different frequency to work so 1993 is different than 1995. There are a few years that things stayed the same, but, not the early years. As I recall the connector is also different and can even vary if you got a replacement updated connector under warranty back in the day.

it was rebuilt about 4 years ago...the rebuilder said he updated something i just can't remember what....it that an update most rebuilders do?...the kit posted above won't take care of that?

WW is correct, but it will still work. I've done a bunch of TCM swaping between year model trucks and they all seem to work fine. I still run a OBDI TCM in my 96 trans.

How'ed gasser run w/diesel tq converter?

94 and older will not fully functionally swap into 95+ without some mods. In 95 GM added the NSBU switch to the trans where teh shift shaft goes through the case. Earlier models did not have the mounting bosses for the switch. The 91-93 units origanally used a different style harness that used a bolt through the middle to hold it in, but many were upgraded as the early plug was a nightmare of electrical problems and leaks. Also the 91-93 trans used a different lockup solonoid as stated, but there were also some internal valve body differences as well. The guts of the 93 trans would easily swap into your 95's case if you wanted to do that, but the bands would be ruined once you took them out so it is sort of pointless unless you needed hard parts to fix a 95's.

Good points, I have allways gone from 93-94 TCM's into newer trans and they work fine. Never went from a new controller operating and older trans.

Another option would be an Optishift controller, but you could use that money to build your trans??
I have the OptiShifts for sale also.
