Hey Brad, do you have the 93 Service Manual? Look through the Trans section ans see if there is a PWM Solenoid...

Pat Same goes for you Boss, Look in your book too

From what I can gather there were a couple of 93 4T60-E'* that used the PWM and one that didn't..

looking thru the FSM

i have found reference that engine speed is used to regulate the PWM Solenoid Duty cycle

the TCC PWM Soleniod description

-Replaces the TCC Accumulator
-is electronically controlled by the PCM
-a duty cycle is used to control the PWM Solenoid. this allows the PWM soleniod to regulate the TCC apply/releasse feel by varying the PWM Solenoid position
-the fail safe actions are
-------no fail safe action is taken but the failure modes are

-------------Failed on (no power, off, stuck open)
-------------------TCC applies with max pressure

-------------failed off ( full power, on, stuck closed)
-------------------TCC does not apply
-------it will function normally again when no faults are indicated
-------the PWM does nothing of the TCC solenoid is off

the PWM can be checked with pins B and E on the trans axle connector

So the 93 Bonneville, all models use the PWM on the 4T60-E?

That would solve 1 issue right off the bat

the 93 FSM makes no reference if certain models have the PWM or not....i would assume that the PWM is used in the 93 Trans

being that the connector on the Trans has 2 leads for testing, id bet that they all have it


Brad Buddy, Make your life easy, i personally think that a 93 trans would be the best way to go at this point

Agreed. And the more I think about it, the more I realize the replacement trans is really little more than a stopgap at this point in time. Just drop out the old, in with the new, rebuild the old and shelf it until the other one craps out.

Which brings me to my final question...would the CURRENT trans work well with an S2, as far as gearing is concerned? Don, we talked about the final drive not making much of a difference, but are there actual gear ratio differences between an S1 and S2 due to the peak torque shift? If I commit myself to an S2 setup, I don't want to waste money on a trans that won't work well with it.

Keep in mind that if I go S2, I would either A) Use 2 megasquirt computers...one for PCM, other for trans duty or 2) Factory S1 PCM with custom chip to drive the S2 engine. Also keep in mind that if I use the S1 PCM, I will not need to run MAP like an S2 PCM needs. (Actually, this is a whole 'nother brainstorming session, so I'll keep the engine ideas separate from this)

i can speak for the gearing

remember the 96 SSEi with the S2 L67 used a 4T60-HD with the same gear ratio as the 92-95 Series 1 L67'*

the difference between the 2.93 and the 2.97 is Barely noticable, you would never be able to tell the difference between the two

Excellent. I wanted to say it would work, but I wanted to make sure.

Time for a new plan - 1)Get 93 trans. IF not HD, transplant HD diff out of current trans just for insurance. 2) Rebuild current trans with all available updates, including new valve body, and shelve until I have an S2 block to mate it to.

Actually, the first part of the plan is to get that freaking house with the garage

The good thing here is that both of these transmissions have an 1897 stall, and like pat said the difference between 2.97 and 2.93 is almost nothing..

UPDATE

Ebay has an excellent trans I can use, and it'* in Jax:

http://cgi.ebay.com/ebaymotors/ws/eB...m=170078923834

5 hours left on it. And since it already is an HD, gearing as stated earlier won't be an issue.

Aside from repin and thermoswitch refit, this will work right?? Only thing I would be concerned with would be axle compatibility.

the gear ratio will be the same....all 4T60 HD'* have the same gear

the internal wring is different, and things you have mentioned already
