Picked up a 4l60e was suppose to be out of a 97 z. It's not. Just trying to figure what it's out of. 3thd165j

thanks john

 

If I remember correctly...

The code "3thd" means

The of production is 2003 for the '3' (could be 1993 but I don't think they made 4l60e's in '93)

"th" refers to the engine/vehicle type

'd' means it's a 4l60e transmission

 

Thank you for your response. The 3 threw me because I don't think they made a 4 l60e in 93 must be an 03. The th is what vehicle it came in. Trying to figure out what it came out of.

Thanks for any help.

 

They made a 4l60e in 93 in the 2wd trucks. It shares the torque arm mount till 97. Just throwing that out there.

 

93 model 4l60 came with 1 piece housing (none removable bellhousing)..03 with removable bellhousing

 

All trucks in '93 had the 4L60E. Only the F-bodies had the torque arm mount on the tail shaft housing (would have been a 700R4 in '93). 2WD trucks and vans did not have them. The bellhousing was not removable in '93.

 

Post a picture of the front of the trans, particularly the end of the input shaft.

 

The Second digit is the Vehicle platform, T would signify 4x4 S-10/Sonoma truck.
S=2wd S-series
T=4wd S-series
C=2wd fullsize truck
K=4wd fullsize truck
B=Fullsize car
M=Astro/Safari
G=Fullsize van
F=F-body
Y=Corvette
H=Holden/GTO

 

Hope this works. The pump does have the pmw on it.

 

Could be 95,96, or possibly '97.
The 96-97 are preferred over the 95. If using an OEM ECU, 95 is all by itself.

 

That is not an LS trans.

 

The d in the code on the side of the trans means it's a 4l60e.

I believe it's a 93 or 03. I want to resell it on Craigslist and want to be able to list it as to what is actually is. Im in need a 97 4l60e out of a v8 Fbody.

 

With the first number being 3 in the id on the pass side of the trans wouldn't that mean it would have to be a 93 or an 03?

Thanks for everyone's help.

 

One piece case is definitely a 95 or 96 with the PWM pump.There must be another code stamped or etched into the case somewhere.

 

It cannot be a '93 because the PWM started in (at least some) '95 and all '96.
It has the 298mm input shaft (LT style, not the 300mm LS style).

As long as it is not a '95, it should work just fine for you as a '97 is also 298mm input shaft, and '96 through '05 are electrically compatible.

 

Thank you mrvedit. I have a 99 ls1 with a yank 3200 stall in a 700r4. According to the folks at yank a 97 v8 4l60e will work with my lt type converter and will work with the ls motor and its electronics. just wanted to make sure before I have it rebuilt. I was ready to throw it on Craigslist but I hope I can use this trans. Thanks again.

 

Yes, a '97 4L60E will work with your 700R4 converter and bolt to your LS1 engine the same way your 700R4 does - presumably with a spacer and compatible flexplate.

We just need to be sure it is not a '95, as some (all?) '95 are PWM but have a different 3-2 downshift solenoid than '96 through '08 transmissions. Drop the pan and remove the 3-2 downshift solenoid which is in front and on the driver's side.

3-2 Downshift Solenoid
------------------------
1993-1995 - White connector, metal stem, resistance of 10-15 ohms.
1996-1997 - White connector, plastic stem, resistance of 20-31 ohms.
1997-2008 - Gray connector, plastic stem, resistance of 20-31 ohms.
(Both White and Gray connector color used in 1997)
2009+ The 3-2 downshift solenoid was eliminated and the trans connector changed

Another way is to also remove the TCC/PWM solenoid which is in the front passenger side. If the two solenoids are identical you have a '95 trans. If they are different you probably have a '96+.

 

If that pump body is original, It is a '96 & up, It has the Bellhousing locating ribs on it, never seen a '95 with that Pump Body & very few '96's (Stamped '96).

The 3 in your code makes no sense....It is definitely not a 2003, It could be a '93 with the wrong pump? Like stated, Pull the pan & see if it even has a TCC PWM solenoid.

 

Yeah, I suspect this trans is a mix of parts from different years, which isn't bad, just confusing.
And good point - you should make sure it really is PWM and has the PWM TCC solenoid. Pics will help an pro builder like Clinebarger determine exactly what you have.

 

So what's up with this transmission and the date code? It has the '3' for 2003 but physical characteristics of a 4l60e from about 1997?
