engine trans pcm question
 

ok my question's are

1. will a series 2 hook up to a 4t60-e trans? ive heard people say you can but im just making sure

2. sences i have a 4t60-e tranny and lets say i have a 99 series 2 motor can i use a 96-97 pcm that has 4t60-e and a series 2 motor?

Not sure what you are trying to do.

In 96 the S2 L67 equipped Bonnevilles had a 4T60 trans. In 97 the L67 had a 4T65.

Yes it's possible.

ok cuz im talking to a guy with a 99 series 2 motor but i dont wana buy another tranny atm so im hoping if i just get a 96 pcm i can keep my trans and not have to swap it

i have a 93 bonnie ssei

You'd have a few hurdles to overcome. Like remapping some of the various instruments etc. Some wire moves at the firewall. With FSM's for both you could definately make it happen.

i would i go about remapping the instruments? and also whats FSM's

Lemme see if I get this right.
You have a 93 car, but need an engine, but the engine you have is a newer Series II correct?
You can pretty much swap any 95 to 2005(ish) Series II engine in any 95-2005 body. It's a matter of swapping all needed sensors.

As far as going from Series II platform to a Series 1 platform, not sure.

FSM=Field Service Manual. In other words, Our Bible.

i can get you diagrams from any FSM from 82-06...

i think the absolute easiest route would be to grab a 95 (or maybe 96-97?) L36 PCM, and just bolt up and go...

ya ill go and grab thoughs fsm and let me recap

i have a 93 bonnie ssei and im looking a a 99 series 2 sc motor for my car. i dont feel like puting a new tranny in atm, so sences 96 ssei still had a 4t60 that the pcm from a 96 would bring the 99 s2 and the 93 4t60 together. so i cna have a s2 reliable care with no ticking noises lol

You sure it wasn't a 4T60E-HD? I know they had those but with special parts to where you couldn't just swap the diff from the 4T60E-HD to the 4T60E. I know for a fact this was the case for the Riviera for that year.

I recommend that you DO NOT bolt a 4T60E to an L67. I had that option with my L67 swap in my 95 Regal and I opted to get a 4T65E. There have been numerous reports of stretched chains in 4T60E's bolted to L67's. The transmission cannot handle the power very well due to that stretched chain. You might get a few thousand miles out of it, but I'd be surprised.

My personal plan of action was to get a 4T65E from a 3100 powered car and bolt the HD differential to it, which will by next week will give it 3.29 gears. Easier on the transmission, and more power to the wheels.

as long as it doesn't get beat on, a 60E will last behind a L67 as long as a 65E-HD...

but who are we kidding here? it's gonna get beat on.

and yes, all L67 cars in 96 got the 60E HD. i'm not sure what all was special about them, but they were 96 only.

Isn't the chain in the in the 4T65E stronger than the one in the 4T60E?

presumably, the dual chain setup in the 65E is stronger.... but that's compared to a regular 60E chain. the 60E HD MAY have a beefier chain... someone who's actually taken apart both HD and non HD would be a good resource here.

I'm positive I didn't quantify it on purpose :) I'm not as familiar with the 60's as the 65's. But in the 65's the trans is a trans is a trans and only a couple interchangable parts make it an HD. Pretty sure the 60 is the same way, except GM changed pitch of pinion, tooth count etc etc, nearly every year. That makes them seem much less interchangeable. But if you know the trans, you can do it easily.

As for chain stretch and the 60 not being able to back up the S2 L67, the issues the 60 has is less vanes in the pump. Therefore at high rpm where the S2 shines the trans cavitates and can't pump enough fluid. The chains are frequently modified to be used in 65's as a single chain solution. Recently with the 5.3L being backed up with a 65, the HV-093 V8 chains were developed. They are supposed to be stronger than the 65's original chains.

There are many faults with both transmissions. I wouldn't necessarily say that either is not suggested. I'd suggest doing the research and learning the various pro's and con's to both, then making an informed decision.

Add power and you can abuse anything into submission. Just ask the various race transmissions that have been behind my engine (aka "Shredda")
