5.3 truck with Impala/Caprice 4L60E

[alfurious]

Does any one know if 2001 Tahoe 5.3 engine will work correct with 95 Caprice 4L60E?
I mean what kind of differeces has Caprice 4l60E and 4L60E with separate bellhousing?

I bought my LM7 engine more than a year ago and still unable to find 4L60E with separate bellhousing

Yes, it will. Read my sticky at the top of this sectiono titled "LS Swap Basics"

First you will need to be sure the 4l603 has the later style plug on it, and then theres an adapter that can be purchased from GM or Hughes Performance.

Huh?

I have an 01 motor in my 94 Silvy with a 94 trans. Plugged right in.

Motor fits well, intake requries body mods to fit. Run a car intake.

Have you reflashed the ECM? or you just use Silvy's ECM as is?

Not sure I understand your Q. The connector is the same. If you run a non-PWM trans (pre 95), you need to change the trans cal and shut off ECCC (Electronic Converter Clutch Control) so that the TCC will lock up. The connector physically plugs in, but the 2001 harness will have 2 more wires in the 16 pin connector, there's just nothing to connect to on the internal trans harness.

I used the 2001 Silvy engine harness. When I had the motor in my 93 2WD Sierra, I used an LS trans and could use the ECCC. When I put the motor into my 94 Z71, I kept the stock trans and shut the ECCC function off in the cal. Most tuners can do that for you pretty easy.

Is there any way I could find out if my tranny is PWM or not?
Thanks for the answers guys!!!

Pull the transmission oil pump off. there should be the letters PWM in raised print on the pump. If it is Pulse Width Modulated, the PWM sign will be on the pump.

Don't need to pull the pump, just need to pull the torque converter. the PWM marking is visible on the front face of the pump.

Do you know if it is possible to convert nonPWM to PWM tranny?
how does it work?
