4L60e/80e Solinoid questions... Any of you guys know the voltage(guessing 12v) and current draw(in mA or A please) of the solinoids in the trans? Also, are there 4 solinoids(one for each gear), or 2 or 3 that are used in combination to select which ever gear? I'm hoping one of the trans. pros here will know.
I've got a prototype built of something, but need to know the voltage and current draw so I can build a driver board to power the solinoids. Any help is appreciated...Thanks.

Here is some info for you. This is some that we use here when testing units on our Dyno. I retrieved this info for you from Zoom technologies, ATSG and Gm hydramatic manuals. It's all a little confusing but I hope this helps. If you need more reference material maybe you should hit me up at the shop. I can make copies of what I have here and also would like to discuss your project. Let me know if you would like to meet up at the shop sometime. Vince

Solenoid A(1-2/3-4) on in 1st and 4th 0.6-0.3 amps 20-40 ohms 7.5 volts or more usually bat V
Solenoid B(2-3) on in 1st and 2nd 0.6-0.3 amps 20-40 ohms 7.5 volts or more
3-2 Solenoid White Stem on when commanded 2nd, 3rd and 4th 0.6-0.5 20-40 ohms 7.5 V or more
Lock up apply solenoid in pump on when commanded possible in all ranges usually only in 3rd and 4th 0.6-0.3 amps 20-40 ohms 7.5V or more
Lock up feel/pwm in valve body Gray Stem same as above for apply 0.0-1.8 amps 10-15 ohms 7.5V or more
EPC always on with power @50% duty 1.8-1.2 amps 3.5-4.6 ohms. 0% duty cycle max pressure 0 amps. 60% duty cycle min pressure 1.1 amps @ 4.5 V

Thanks, that's exactly what I was looking for. I'm pricing a few components and just wanted to make sure the solinoid didn't draw more than the MOSFET driver could handle. But it looks to be well within it's limits.
Once I get it together and working right I'll have to get in touch with you.
