I have been looking for a nice 4T60 for my 88. They are all high mileage and will require an overhaul. I can find the 4T60E everywhere for cheap , and with low miles. Same mount brackets and shifter brackets are used on both for Fiero applications.

I read here once where it was said you can piggy back a 4t60E ECM to control the transmission, A second temperature sensor would be required I am thinking was mentioned.

Anybody done this. If so where did you place the second ECM? Are any of the 4T60E ECM's mountable inside the engine bay?

16149396 ecu. Used with the LQ1 3.4 TDC engine. You could also use the Megasquirt GPIO with the Megashift code, or a microsquirt with the same code.

The 9396 is an outside mounted ECM?

Yes it is. I have 2 in my Landcruisers. I have forded rivers over the hood and never had a problem with the computer. Now the passenger was a different story.

Found these on E bay for reasonable amounts. Use this to control just the 4T60E, or both my v6 and the 4T60E? I have a 3.4 dressed out as a 2.8

With a bit of tuning, this would work. Biggest change would be to change the ignition timing parameters to match a distributor considering the code is set to control a DIS system. Not a big deal though. Other than that, you could use the 3.1 version of the $DF code to start with.

Will the 1227165 shift a 4T60E?

Personally I would just use the additional ECM to run solely the transmission, but that's just me.

There is gotta be a easy efficient way to do this and get away from the non electric versions of the 4 spd OD automatics.

No, no, and no. The 7165 does not have the hardware for it.

I wouldn't have a clue on how to do this. Seem like those who know, give very scant clues.

I will help you wherever I can. Where do you want to start? Also, PM is coming your way.

If you use the 16149396 solely you can mount it in the stock ECM position.

There is no benefit of mounting the ECM/PCM outside if you can fit it inside.

Yes there is! Larger then stock ECM's will get too hot under the console with higher power engines (aka more heat), even more so with the insulation there. Like a 3800 series 2 ECM.

I purchased me a 16149396 ecu on E BAy today. $30.00 shipped with the connectors and 4" of wire.

Im watching intently.

My formula has a 4t60. It's great for a D/D because it gets me 26 MPG at 80 MPH. However, it sucks for trying to race someone, the shifts are too uncontrollable.

This car has a 4t65e with lightning rods in it. I dont know how he did it but I can get ahold of him.

88 formula 3.4L 4t60 swap

Let me dig up some information, but there is a way of using a diesel 4l80E trans controller to control the 4t65e. Could also use a 16197427 PCM as well.

Just got an E mail reply from Ryan from Sinister Performance, asking for information..

"You might be able to use a 16149396 ECM to just control the transmission. It will need its own coolant temp sensor and it will need to share the TPS, MAP, and Ignition Control Reference Pulse signals going to the Fiero ECM. Of course the mem-cal/chip will need to be reprogrammed."

Seams to me that the best place to put the 2nd ECM would be as close as possable, or, behind the driverrs seat. This is close to where the 2.8 wires go into the Fiero ECM. A great place to 'Leach' sensor signals. 9 sensor wires, plus a few ingition 12+, a few +12 at all times. A few grounds. 7 wires going to the transmission's TCC connector. 2 of which are already there.

I have learned that the 16149396 ECM is an odd ball. It will work on two 4T60E's made for 1993. A 3.1, and a DOHC 3.4. Will not work with the rest. Something to do with the 1st gear and 4th gear switches. These two 4T60E's are not as plentyful as I was hoping. I have purchased a 16196387 including connectors, out of a 95 Buick Century. It will work with just about every thing else 4T60E. Located a 1997 90K 4T60E in Houston for $200.00

How did this work out?
