If you get a auto transmission moving fast enough you can start the engine. I do not think is is good for the transmission.T56 it for that bump start baby, never be stranded again
"GM did make 3 different starters for these cars, all of which will fit any lt1 or the 4.3 version of the engine. F-bodies all got the SD-210 model starter. While B bodies got the SD-260 if equipped with the 4.3. All wagons got a PG-260 starter and Roadmaster & caprice sedans got a PG-250. While all starters are gear reduction type and look mostly the same the PG-260 is actually physically smaller then the other types. This info taken from 94-95 GM factory manuals."
From what I can tell digging around on ACDelco.com, Caprices and Impalas used the PG-250 in '94 and '95 and switched to the PG-260 in '96. Cameros and Firebirds use PG-250 in '93 and '94, switching to the PG-250 in '95. They are both gear reduction models, but the PG-250 is rated at 1.4 KW, while the PG-260 is a little more powerful at 1.7 KW. The location where the starter wire and battery cable attach is slightly different -- the whole solenoid assembly appears rotated by about 60 degrees.
EDIT: assumptions made in this post are WRONG.If you get an auto transmission moving
you can start the engine. I do not think is is good for the transmission.
So... Is that a yes or a no?To do this, the road - the pictured hill, or some schmuck pushing/pulling the car would have to do so
with the UNpowered UNlubricated transmission in gear, so that when the road finally gets the engine spinning
the starter has little or no work to do to start the engine - and remember that the transmission must be shifted BACK into neutral before starting the engine, which is hopefully still spinning
I do not know how fast an LT1 engine must be spinning before the pcm decides to add spark and fuel.
Of all the crazy things the ISSF has tried, I know of no one who has tried THIS, and with damn good reasons, not the least of which is that the 4L60E was never meant to be in gear unless the trans pump and engine are on.
When I had to shuffle the cars around in the 1980s I would start them by rolling down the driveway. We did not have "battery tenders" and multiple starts without driving ran down the batteries. A good motor starts easy. We assumed the drive train could take the shock or the tires would skid.Neutral safety switch prevents starter from operating ,not the motor. if that's what you're thinking.
Should jump-off in any gear desired with ignition on.
I know what you are saying is correctRear pumps in GM car transmissions stopped in about 1964ish.
Had an aluminum " glide" in a 63 that you could still push start.
Th350s, th400s, 700s, etc, never had rear pumps, impossible to push start.
I dont know the exact threshold but its pretty low as you get an impulse bench testing an optispark and pcm slowly turning it.I do not know how fast an LT1 engine must be spinning before the pcm decides to add spark and fuel.
the 4L60E was never meant to be in gear unless the trans pump and engine are on.
If you are saying you can tow or push a 4L60E car to a speed that the stationary engine will start when you select a forward gear, in the most friendly way, I challenge you to do so.Can it be done?
Given enough road to get the engine up to speed, YES.
ONLY IFF given sufficiently controlled conditions would I dare to accept such a challenge.If you are saying you can tow or push a 4L60E car to a speed that the stationary engine will start when you select a forward gear, in the most friendly way, I challenge you to do so.
I do not think this would start it.Drive your car at freeway speed, put it in neutral, let the engine idle, shut the key off, let the engine stop turning.
Turn key back to on, verify engine is not running (oil light, alt light on).
Pull it in gear, does the engine start turning and start?
Oh I think not
I stand well-corrected.What is it that makes you think the engine will start turning?
The pump that makes pressure to engage clutches or bands is directly connected to the crankshaft.
If the engine is at rest, there is no, pressure, no engagement, no connection of driveshaft to crankshaft.
