What if, Black Box PCM repurposed as TCM?

**LRT** · 01-04-2016

The intent of my original comment was to help keep costs down. These projects have a way of spiraling out of control. It is amazing how $100 here, and $300 there, becomes an additional $10,000 in what was often supposed to be a low dollar project.

By the time you upgrade the S10 4L60 to 4L65 specs (not a full rebuild, just a hard part upgrade), and purchase the flexplate / spacer kit - you will have exceeded the cost of a good used LSx 4L65 - and would still not have a completely comparable transmission.

My two cents is either sell the LY5 (Gen 4) engine and purchase a Gen 3 engine, or sell the Gen 1 style 4L60 and purchase a Gen 4 style 4L65.

Just trying to highlight some potential hidden costs, not trying to derail Dave's thread.

I appreciate ALL the input I'm getting!

My current thinking, which may change:
Use the LY5
Use the 96 4L60E
Use a 1 meg DBC PCM with L33 / 4L60E modified Flash
Use L33 knock sensors
Retain the Black Box VCM

DBC is possible with a 1 meg PCM. The 96 4L60E should be compatible with a 1 meg 4L60E PCM programming. The Lingenfelter 58x / 24x conversion should be compatible with a 1 meg PCM. The L33 Flash will have native knock sensor programming to match the L33 knock sensors. The L33 Flash should be close enough to run, then tune to the LY5?

I'm responsible the harness and flash for this project (the easy stuff ,

) which is why I appreciate ALL the input of this thread.

FYI Dave, I just wanted to let you know that your LY3 5.3 with its rating of 315hp@5200rpm/338lb/ft torque@4400rpm originally came with the rpo-M30 4l60e and not a 4l65e rpm M32.

Since the 6 cylinder and 8 cylinder 4l60e is one in the same, you aren't asking the trans to operate outside its design parameters. Not too say the trans will be bulletproof, but your light vehicle weight is going to help the trans survive. If you do ever rebuild, don't just install the 65e parts, its a marginally stronger trans.

I have blown both of them up with a ~300 HP 350! 4L60e and 4L60E built to 4L65E specs with 4L65E hard parts.

The factory 4L60Es in my brothers 99 Suburban held up for about 15K before he sold it, but also had the command shift times set at 0.3s across the board and had 30% torque reduction from about 150 ft/lbs and beyond in all 3 upshifts and 2 downshifts. I have the same exact transmission tune in my brothers 99 Tahoe behind a cammed L30. The suburban had a DCLF converter and the Tahoe a factory. The Tahoe shifts noticeably firmer because of the tighter converter.

I'll have to pop back in and read through all of it,but it should be very possible.
As I recall Street and Performance in Mena,Ar did thier initial LS swaps this way or similar.
When the 0411 swap project was going I recall a couple of us sending emails to them both asking about how they did something that pertained to the 0411 swap as well as attempting to convince them there was no reason to run two pcm's.
I don't recall what platform it was though,LS/vortec or LT1 swap. I want to say it involved swapping the LS into a vortec truck but not sure it was prob 8+ years ago.
Maybe Pauly or Jeff recall it.

**dave w** · 02-04-2016

I searched Auto Trader for a couple L33 VIN #'s:
1GCEK19B85Z328182
1GCEK19B65E281547

I would greatly appreciate help confirming the above VIN #'s are from vehicles with the L33 / 4L60E powertrain.

I plan to purchase a .cal from TC. I'm wanting to make sure before spending the money.

Both 2005 4x4 l33 engine trucks. I dont believe the l33 came with anything but the 4l60. If you have an existing 5.3/4l60 file why not use that? Minimal difference between them.

I don't have an existing file, so I plan to buy one from TunerCats.

I need to make a correction to the above comments: The L33 uses resonant knock sensors.

Are you referring to the 4L80E? It remains a 1-piece case, probably until EOL. If you are referring to the 4L60E, then I'd like to see a 1-piece case in anything newer than 2002. :-)
