6.0 swap

[USMC09]

Hey i have a 93 silverado and i was looking into a Gen III 6.0L swap. Does anybody know if this is possible with the stock transmission and rearend? I know id have to gut the computer, but will the other stuff work?

-thanks

Yes, you can use your old transmission but it will be blown to pieces in no time at all. If you want to use it, have it rebuilt with better hard parts. The rear end will work, also. That's the same thing I have only you'll have a few more inches on me. You'll definitely want to put in a limited slip diff.

so ill just need like new gears for the transmission or what??? also, what kind of rearend do you have?

[RedHeartbeat]

You'll need an adapter/spacer for the flywheel to use your old transmission unless you run a 99/2000 6.0L with the wide crankshaft flange. Check out www.hotrodlane.cc for some cool parts for the conversion. For the transmission I would suggest you get the internals upgraded to 4L65E parts with 5 gear planetaries and a Beast sunshell. Your third gear clutch set should be replaced with borg/warner clutches and steels from the 4L65E to handle the torque. You could just buy a 4L80e with the 6.0L engine and harness and be done with that part. You'll lose a few HP turning that big transmission but you'll have plenty transmission to do most anything you want with the engine.

cool. sounds like it might be cheaper to just get the new one by the time i pay for labor (i am no good with auto transmissions). for the rearend i can just get off swappin the guts then huh? also, how does it work when u get the new engine computer....arent there problems with gauges and brakes and transmission stuff? I know my truck has RWAL, will that work with the new computer?

oh yea thanks for the help

[RedHeartbeat]

Yeah, just swap out the third member. The RWAL will work if you wire in the speedometer sensor pickup from the transmission into the little white box behind the glove box. That is the speedometer calibration unit plus it feeds pulses for the cruise control and antilocks. Use a stock oil pressure sending unit. If you had a tach you'll need a converter available from BakerElectronix.com. For water temp, drill out the passenger side head at the rear where the plug is screwed into the block and use a factory unit from your 93. The 1998 LS1 three wire unit must have the wrong resistance because my autotap and PCM don't agree with what the dash guage says so I would say go with the 93 sending unit.

so what kind of motor u got in that maroon truck?

nevermind......dumbass question

[USMC09]

hey does anybody know the model name of the stock transmission on a 93 silverado? I was tryin to look up parts but i dont even know what the transmission is named

[RedHeartbeat]

That is the 4L60E transmission. It's what was in mine unless yours was an exception to the rule, maybe an early 93.
