Just order a reman from Jegs(ATK) for a 94 GM 1500.. They even have units that are bumped mildly in strength for towing.
Used transmissions are crap-shoot at best.

 

I completly agree maroon just being a self important ***** all these transmitions are very similar and I still didn’t get a satisfied answer and I’m fairly knowledgeable.anyhow I got a 98 4l60e with4 bolt transfer case flange that I bought by mistake but wondering if drum pump ect will fit in my 2001 sierra 5.3 six bolt transfer case flange?? Sorry if dumb already answered question moron…..and I have a 2wd 2005 4.8 will that torque converter work on on the 2001 5.3 ls? 5.3 is of course 4x4 and both trans in quest are 4x4 except4.8torqueconverter is off 2wd. confusing yes basically I’m asking if drum and drive internals off (4 bolt transfer case flange)98 4l60e will slide into the (six bolt transfer case flange) 2001 5.3 ls if that makes sence…

 

Maroonmonsterls1 is very blunt sometimes because the same questions get asked over and over. They get answered over and over too. It is frustrating to see a question asked that has been answered, especially if it is in the same thread that actually has the answer. That just tells us that the post was not actually read or the material in it did not get fully comprehended. This is also a 4 plus year old thread.
To answer your question as best that I may...
The LS based units have a bolt on bell-housing, it uses a casting # 24206952. It can be viewed from the outside of the bell-housing over the starter pocket. The quick tell is the top center bolt, It is 5/8" deeper than the Gen II SBC version. All bolt on bell-housing 4L60E's have a 6-bolt extension housing/TFC mounting. The LS based units also have a longer stator shaft for the pump & a Input shaft with splines at the end & the TCC o-ring behind the splines. See this thread post # 2

Most 4.8L engines use a TMBX converter, it is also used behind 5.3L & 6.0L engines. It has a 1400-1600 factory stall. There a a few that use a different stall of 1600-1800 but will interchange. If a 1400-1600 stall is used when a 1600-1800 is needed it could create a slight difference in take off feel.

The Gen II SBC version 4L60 carry's a 24206579 casting #. This unit has a input shaft with a tipped end that has an o-ring on it. The splines are behind the tipped end. See this thread post # 4.

The 4L60E one piece case models have a 4-bolt extension housing/TFC mounting. They are 100% incompatible with an LS based unit. That is unless you want to buy a specialty TFC adapter, have both driveshafts rebuilt & modified.

If you really want to understand the evolution of the 4L60E see this post over on the S10 Forum...

If Tranzman had not answered you promptly, I would have deleted your nasty post and temporarily banned you from this forum.
A total newbie DOES NOT join this forum (or any other) and immediately bash one of the undisputed experts and major contributors without consequence.
Iff you are normally polite and respectful, you are very welcome here.

 

I'm pretty sure that's a bot. No punctuation or capitalization, run-on sentences, very first post...

You should probably ban the account on general principal, though.

 

I think its a real person but with intentional way of writing to throw people off IMO, Aparently with some issue with MaroonMonster.
But I agree that Maroon is one of the most knowledgable here, And I do understand his frustration at times, While I have not experinced to here I have been spending some time in the FaceBook forums and OMG sometimes you just wanna scream at the questions same over and over and over accompanied with the YOUTUBE/FACEBOOK experts some only been doing this a few years or less acting like they are the know all be all.
I also agree with EDVETTE the regular contributors here who do take time to help and answer and have published in some cases gobs of good info deserve the upmost respect at all times. This forum and this section is likely the foremost place of information about in particular the 60E on the entire internet IMO.

 

I was just ignoring the guy. You can't come in here with your very first post and start disrespecting members, I don't care who the member is. Tranzman is more compassionate than I am, which is a good thing.

 

Yea that maroon guy sucks!

 

Hey its all good I get told I suck all the time, Its the sign you are doing something well when people hate you lol .

 

People these days get their feels hurt very easily. If you don't coddle or give them what they want, they get all upset. As a young kid working a part time job while in high school, I had the opportunity to work with a few men that were up in years. Let me tell you those guys said whatever popped into their mind and if it hurt your feelings that was just too bad. You learned to toughen up really quick.

 

I grew up having to hold the flashlight for my dad!!! As a youngster I worked with an almost constant harassment work places. Most times it was in jest. Sometimes its like the comedian taking all his jokes out on an ethnic group but you have to laugh because it's true!!! Sometimes it was just the plain truth and it hurt but helped me grow...
I love this forum but hate the I want to be spoon fed attitudes. Everybody has 168 hours in a week, some cant manage it at all and believe they are to busy to read/study something that would help them.

 

Wondering if a ‘97 4l60e 4x4 trans can replace a ‘02 4l60e 4x4 transmission. Any help is appreciated.

 

Read my posts #2 and #4 carefully again.
A '97 is definitely a 298mm input shaft trans. A '02 4x4 is likely a 298mm trans, but not sure. Tell us what '02 vehicle it is and perhaps one of the builders here will know for sure. Else we need pics of the '02 trans bell housing top.

 

02 unless a 4.3 would be a 300mm . 97 298 as @mrvedit stated, Can you swap it in ? Sure you will need a spacer adapter for converter this assuming it is a removable bell type of course as in 97 both happened . So if it has a 6 bolt 4x4 adapter and you want to get the spacer yes you can do it.
If its a 4.3 litre would be direct I think but they did change that too but cant remember when exactly.

 

In 2001 GM started using the LS based transmission even in the 4.3L 4x4's in full sized trucks. The only thing that continued the 298mm input was the S10/Blazer series.
So the short answer is, no it won't work!

 

Corvettes also continued to get the 298mm input

 

Good to know! I just haven't done any Corvette units after they got the LS engine...
