Yes. The 4.3 engines are the same offset as Gen I / II (SBC) engines which all need the adapter.

^^See if you can figure this out..

In my 1991 S10 I'm using a 1999 V6 S10 Trans and a standard LS Flexplate with a 700R4 Convertor(smaller diameter and PWM elimated), no issues, cleared properly. Had 1/4" from the Flexplate to the Pads with Convertor fully seated. Been driving fine for a while now.

A 1998-02 2wd Truck Trans will work with a F-body, all you have to do is swap the Linkage Arm and the Tail Shaft Housing if your Torque Arm still bolts to it.



Your best bet would be a 2wd 1998-02 Truck.
I have 2 of them cores myself..one a friend gave me when I did a M6 swap into his truck, and the other is my old Auto from my Camaro, it has all kinds of good hard parts in it(Beast Sunshell, Super Servo..etc..), the Clutches/Band are gone. I'm combining the two and building a badass pulling Tranny for my Truck. My Camaro one has a Corvette Valve Body..it

Hi I am swapping a 5.3 into my t/a. It's from a 2wd 04 Silverado and I got the 4l60e with it.... I want to use the 04 trans to have built to handle more power while still being able to drive my car, what will I need to make it work? My torque arm is already relocated so that is not a problem.... Thanks!

Okay I have a question I have a 94 Chevy Silverado extended cab it currently has a 350 TBI motor I am planning on doing a 5.3 or a 6.0 LS swap it has a transmission out of a 93 Sierra GT it might be a little newer or older but not more than a year or two can I use that transmission and is it just the spacer and flexplate? Or will I have to get a different transmission and if I can use that transmission what all will I have to do to use it

I currently have a 94 Chevy C 1500 and I'm planning on doing a 5.3 or 6.0 swap it has a transmission out of a 93 Sierra GT the trans maybe a year or so newer but can I use that transmission or will I have to get a different one? And if I can use that transmission will it just be the spacer I have to get in the flex plate or other things too? And will that plug right in? In what wiring will I have to change on the stock LS harness for the transmission? Or would it be better to get a transmission controller? Any information would be awesome thank you

If it all possible I want to use the transmission I already have because I'm on a very tight budget and will end up switching the transmission later probably or having the one I have built a lot better I just want to know if it's possible to go ahead and use it and maybe how to do it and what all parts I will need

yeah basically you need an 80e flexplate and spacer. google up mating a gen 2 trans to a gen3/4 ls type motor. lotsa guys putting in 350's 400's 700r4's etc..

but my experience has been its not IF but when the 4l60 will die. IMO you can save a lot of hassle by sellign that thing off to someone who needs a direct replacement. then take that money to the pick n pull and grab the first 80e you find '97 or later that isnt full of busted metal in the pan. grab the slip yoke too.

the overall length is the same between the 80 and the 60, so swap the yoke, move the crossmember back, do some very simple repinning and a segment swap in the computer and never look back

Default 1994 Camaro z28 ls swap

I'm having issues with my transmission mount lining up with my torque arm relocation crossmember . Its off maybe by one inch or inch and 1/2. Has any one else had this issue if so what is the best crossmember to use. My set up consists of 1994 z28 with truck 1999 5.3 and 1999 4l60e. I also swapped the LT1 k member for a Ls1 k member. Om aware that the 1993-97 and 1998 -02 transmission cross members are totally different.

Is that a stock LS1 K-member you installed, or an aftermarket piece?

Is the trans mount landing in front of the mounting holes in the crossmember (too short), or behind the holes (too long)?

Here's where you weld a piece of 3"x 3" angle iron to the back of the crossmember, drill an appropriately-sized hole in it, and bolt the tranny down! DONE!

I'm going to make some assumptions from your photos and you can confirm if those are correct or not. 1.) You are using a stock LS1 K-member and stock LS1 engine mounting stands to mount your engine. 2.) Your transmission crossmember is from UMI Performance. If that is correct than your issue will be related to mis-matched parts more than likely. The UMI Performance part is listed as being a torque arm relocation crossmember for stock 1993-97 F-body automatic transmission applications, not for LS swap applications. There are two issues you are fighting, the first is the fact that the stock 4L60E transmissions used in those cars had the transmission mount located in the transmission case (the transmission case is a one-piece casting, unlike the later type of 4L60E you have which has a bolt-on bellhousing), not further back in the extension housing like the one you are using. The second issue is the fact that GM moved the engine/transmission mating plane forward in the car by about 5/8" when they started putting LS engines into 4th-gen F-bodies in 1998.

When that change to place, the 4L60E transmission was changed to the multi-piece design and the distance from the face of the bellhousing to the trans mount increase by about an inch (the mount attachement location was moved to the extension housing like it is on your transmission. In order to address the issue you are having, you'll need to modify the crossmember you have (i.e. make a rear cantilever bracket for it), or use a transmission crossmember specifically designed to pick-up the mount on the later style multi-piece truck 4L60E trans mount with the engine being mounted in the fore/aft position dictated by using the stock LS1 K-member and engine mounting brackets (I'm assuming you are using the stock mounting brackets). The Hooker Blackheart 1993-97 F-body LS swap transmission crossmember I've posted a picture of below is specifically designed to do that and there is a separate torque arm divorcing bracket that is also available to use with it. The crossmember can be used to install about 4 or 5 different transmissions and the 4L60E transmission requires a specific cantilever bracket that is visible in the images.
