Pre-LS swap questions

[Root2812]

Hey guys,

So this weekend was supposed to be the weekend of progress on getting the motor all cleaned up and what not. Unfortunately my 2000 GMC Jimmy decided to suffer from the all too common bad injector spider. I ended up spending my Saturday replacing that spider with the upgraded Multiport FI system.

Anyhow, my new intake did arrive and was in good condition. The guy I got it from didn't ask me to send the broke one back so now I have 2 sets of fuel rails, throttle bodies, and injectors. Spare parts may be useful later.

I also have been giving some thought to what has been said here by all of you and I am going to go with the 4l60e instead of the 700r4 I already have. It came down to easy of hook up with out having to deal with a tv cable and the fact that by they time I buy the adapter kit and tv cable I'm almost to the cost of the 4l60e. I just gave the 700r4 to my dad. Its going to go in a 57 bel-air behind a 283.

So here is a question. I have read that there are many differences in the 4l60e's. Could I run one that came out of a 2002 with a 4.8 when my motor is a 2000 5.3? I think I could but I want to check with you guys first. A local guy has that tranny in 2wd with 130,000 for $400. I can get him to come down. Up here in the north the 2wd trannys are harder to come by because most guys buy 4x4 trucks.

Thanks

That transmission will work no problem. If it was from a car you would have to change the tail housings but there is no difference between a 00 and 02 2wd transmission. Good luck with the build! Can't wait to see more progress!

huh?
You would only need to change the tail shaft housing if it was a 4wd tranny, the 2wd tranny is fine as-is. The other tailshaft change was switching to a 6bolt talshaft housing for the 1998 revamp. That would only apply if he was trying to use an old 4l60e, which would also have a 300mm shaft, different planetary etc etc.

and no car ever had a 4.8 or 5.3

If you re-read my post I clearly stated there is no difference between a 00-02 2wd transmission. I should have been more clear and was just stating a fact the if the trans came from a car, more specifically an f-body, you would have to change the tail housing.

oh and the 06-07 monte carlo ss, 05-08 Grand Prix GXP, 06-09 Impala SS, and 08-09 Buick lacrosse had a 5.3. jus sayin.

torque arm brackets can be added without switching the tailshaft housing, and none of the cars you listed used a 60e.

I suppose you wouldn't have to change the tail shaft housing if the torque arm bracket wasn't going to be used. And you said no cars came with a 5.3, you said nothing about them having a 4L60e...

As for the torque arm thing; you still wouldn't have to change the tailshaft housing even if you did need to run a torque arm mount (which doesn't apply). There are relocation brackets and crossmembers designed for the cars that DO use torque arms. The tailshaft mount torque arm brackets can brake housings in high power applications, it wasn't the greatest place for it to start.

Remember the context of the thread; he asked a trans question about the 2000 and 2002 4.8 and 5.3 in question. There is no car with a 4.8 or 5.3 that could possibly apply to his situation, they all used the fwd configuration. Further, those all use the ls4, which isn't the same as the iron blocked 4.8 and 5.3 we are all referring to. It doesn't even have the same bellhousing pattern.
Don't get lost trying for a pissing match, its not helpful to the op.
