4l60e transmission question

[On3honksgo]

My transmission went out in my 98 tahoe today, what other years 4l60e are compatible. Im hearing 98+ are different??? Is this true, i have called multiple trans shops and researched, i cant get a straight anwser.

Just need to know what years i have that are compatible

 

[ccapehartusarmyINF.(ret)]

the turbo700r4 was renamed the 4l60 in 1990 and in 97 they came out with the electronic controlled 4l60e

The 4L60E featured a three-piece aluminum alloy case that consisted of the main case, tailhousing and bellhousing. It was 21.9 inches long with a 30-spline input shaft. It had a square oil pan. Pre-1997 4L60E transmissions had a four-bolt square pattern on the case cover, while the post-1997 version had a six-bolt hex cover pattern

they did not do anything to the transmission in 98

So ill have to find a 97-99 4l60e is this correct then

97 till 2006 is when they stopped putting it in vehilces
just get one out of a similar vehicle tahoe suburban or pickup
i think they differ from model to model like a 4l60e from a corvette is very different then a tahoe one

i think the only differnce in the truck suv 4l60e is the4x4 and 2wd model

they change the bell housing/case setup in "98 and it uses a bigger converter. anything 98-2000 will drop right in1997 or older may require some extra donor parts.
