99 Tahoe transmission compatibility

[nidex]

Hi everyone,

I need to replace a transmission on a '99 Tahoe 4x4 4L60E, push button 4x4. I have done a little bit of research and I can not get a straight answer on what year transmissions will work with this truck.

From what I have come to understand, the 98+ have a 5 bolt tailshaft connection to the transfer case, whereas the 97 and olders have a 4 bolt. The 97 and olders also have a 1 piece trans, where the 98+ have a removable bellhousing. I have heard the 97 and older have slightly different shift points, which I don't care about. It appears that I can only use a trans from a 98-00, not a 97 or older, which makes things slightly more difficult because I have the ability to get a 97 trans for a good price.

With that said, I have also heard/seen a lot of people say that the 97 will work just fine- as long as it has the 20 piece connector where the harness plugs in.

Can anybody give me a straight answer? I don't want to go drop a bunch of money on a trans that won't work.

Thanks in advance!

i picked up a 99 4 door and am wondering the same thing. my trans shifts really hard into 2nd and then fine after when hot. dont do it all the time either and i have noticed once i shut it off and restart it it stopped as well. im had planned on just having it rebuilt at some point but if ther are options i would like to have them to consider.
