So the 4L60 TCC would be stuck in a LOCKED position while unplugged?
That's a stupid design. But wiring up a manual lockup switch wouldn't be a big deal.
That would save me from shredding planetaries on the dyno I guess.

nope. lockup will work totally fine.

the other parts of the trans such as the pump, valve body, wiring, and seperator plate are different and it will bleed off pressure and kill 3-4 clutch pack over time.

it cannot be used. end of story. either get a 96+ trans or convert yours to a 96+ internals

I'm getting one lined up.
There's no point ruining perfectly good 4L60.
I just wanted to get the engine and PCM working before I tackled a tranny swap.
Being able to drive it to my friend's lift would make made the swap a lot easier for me.

Who is going to offer to rework the used harnesses? I've not yet heard of this.

Why would the 4L60 ruin the 3-4 clutch pack? It's controlled by the TV cable unlike the 94+ that is run by the solenoids. The only electrical connections on the 4L60 are for the TCC and VSS. Aside from that it is run off the TV cable to adjust line pressure. Unlike the 94+ that runs off solenoids.

There is no reason that a 4L60 should not survive even with the LSx PCM swap as long as it has a functioning TV cable. All the LSx PCM would do control the TCC which shouldn't be that big of deal.

If you actually care to read up on this topic then come in here and bash then you will see it pertains to a 94-95. We are talking about the 4L60e here.

This is going to be my last post on this topic. Im sick and tired of trying to help people out on this board over this trans topic, when I constantly get either questioned or bashed. I am done now, I hope you guys learn for yourselves one way or another.

I understand your frustration, but I think we are on two different wavelengths.
Sorry for getting your thread off topic. I have a 93, and thus a 4L60. I will swap in a 96+ 4L60e later.

A friend of mine, he's doing mine right now. It was in great shape so saw no reason not to use it.

Honks, I was refering to exactly what James was talking about. I completely understand what you are talking about with the mid-year 4L60E's. It makes perfect sense. Since I have a 93 as well I was just making the point about the slight difference.

James, no problem man. Personally I say just build a wicked 4L60/700R4 and not even worry about letting the pcm control it. Since the only thing different internally is the solenoids, your 60 should be just as stout as any 60E anyway. That's me tho. G/L with the swap!

Agreed, but tuning shift points with weights and springs sucks.
I'd much rather be able to command shifts at a specific RPM.
Either way, the tranny has to come out.

Agreed! I pulled a fresh 700R4 out of my vehicle after the 24x conversion because I was so frustrated with shift points. I LOVE the 4L60E!

Hate to drag up this old thread again, but I just have to say that my '95 4L60E works great with the LS1 computer, just had to change one solenoid and the internal wiring harness. Been almost 10K hard miles with no hint of transmission failure. Like I said earlier, it's not rocket science....

better to ask here than create a whole new thread


will the truck coils/coil harness work with the kit?
if I'm staying with the LT4 chain, will a 97 front cover work?
is the 24x reluctor wheel custom made for the LT1s or is it a part I can find in a junk yard?
I've looked and cant find the DIY harness kit - can someone PM me a link?

TIA

I used LS2s, might be able to use truck coils, not sure since I used LS2s.

Yes, some one makes a billet single roller as well thats suppose to be a good piece. Option if you went with an electric water pump like most folks do.

is the 24x reluctor wheel custom made for the LT1s or is it a part I can find in a junk yard?

Custom made by a company called EFI Connection.

I've looked and cant find the DIY harness kit - can someone PM me a link?

Google the name of the company where you can get the reluctor wheel from.

You can use truck coils. I did at first, they work just fine.
