AT push-start? 4lo+1st+big hill??

[Max Power]

anyone think it would spin the engine? I don't want to carry another starter, and I'm just thinking worst case back country scenario..

Thanks

I didn't need the 4lo. I had to roll start my dearly departed Blazer once, many moons ago. I put it in "1" and rolled it down a steep hill out in the bookcliffs in Western Colorado and it fired at around 25 miles an hour. I was thinking of doing a tranny drop but decided that a tow was cheaper than a tranny.

Doesn't work that way. Torque converter doesn't work backwards.

Well, the torque-converter "sorta" works backwards, enough to bump the engine. The trouble is that the clutches require line-pressure in the tranny to engage, which has to be built by the tranny pump. The TH400 and newer TF727 only have one pump, and it's at the front of the tranny, not being turned by anything when the driveshaft is rotating.

Older TF727's had a rear-pump, so they could develop pressure to engage the clutches and turn over the motor from a push-start.

If you started the Blazer with a push-start, it must have been because the incidental friction between the steels and the clutches at that high a speed was enough to start turning the motor. I'm sure that tranny didn't appreciate the effort... smile.gif

In fact the 727's with the rear pump have not been manufactured since 1965. All 1966 and newer 727's have only the front pump and should not be push started.

I remember my uncle had a 68 corona with a toyo-glide that could be push started. It had a front and rear pump. But from what I have heard (havent actually seen) is that you can damage the tranny by trying to role start it.

Yet another reason I love my sticks smile.gif

Torque converters don't work backwards, definitely not enough to start an engine.

Starters don't go out too often. I usually don't worry about it. But carrying a spare isn't too expensive and it doesn't take up a lot of space.

[gsmikie]

you can only push start a automatic in your dreams.......................

[Stuka]

if it has a rear pump it can be push started. Otherwise no.

[J20 project]

Back in the old days we used to do it, they were early 60's vintage cars though. Later than that, it doesn't work. J20

But, on the bright side, if you are pointed in the direction you want to go, you will be closer to where your going once you stop.

Carry the starter.

[Max Power]

My old starter did fine on the water crossings, but them my solonoid died, and I upgraded to the 'mini hi-torque starter w/ integrated solonoid" it cost considerably more than the stock starter and weighs considerably less, its a great little starter, but I can't afford to buy another one just to carry... and I'm not carrying that hugh jazz old starter.

thanks for all the info and opinions, you guys are great!

[MIDLERTH]

In my 81 manual it says it can be pushstarted but it is not advised.I wouldnt do it anyways, sounds to risky.

[Stuka]

oh ya, just remembered something. Saw a rock crawler with a 700R4 with a manual lock up converter (wired it to a switch) so it can act like a manual. And it can be push started.

[Stuka]

well

i didnt mean as a stick per say. i ment as in it had a direct lockup like a clutch would.

Then, on the other hand, you could just put all the spare parts together and then you would have a wheelin buddy to go get that starter when it goes out tongue.gif

I don't take my automatic out in the boonies.

I do always carry a spare belt, hoses, full distributor setup, solenoid, toolbox, rope, 20,000 lb rated ratchet strap, {normally used to strap lumber on flatbed}, 2 tires, mini welder, duct tape, 1 lb bag of dubble bubble chewing gum, 2 giant hershey bars, 4 milky way bars, 4 gallons of potable water, loaf of bread, jar of PB, 9mm handgun, retractable 22, first aid kit,
and 1 headlight.

Forgot the set of U joints and 1 set of opposing flexable brake lines.

potable water? does he mean patatoe water?

i also carry both driveshafts, and enough fluids to change if somthing happens. 4 qts oil, 2 pints gear oil, a few of tranny fluid, brake fluid, ect.

[Bo]

Potable water is water safe for drinking.

You can cook potatoes if you want. ;)

If you dont take the body fluids for the vehicle you probably shouldn't be out there.

hey bo, I'm more of a snickers fan, I'd appreciate it if you'd add several 'king size' or 1 bag of 'fun size' snickers to your list, preferably the latter, also some coors for after the trail ride. Additionally I prefer 38/.357. but besides that, I wholehearted agree with your list!

[Bo]

You would need to bring the Coors.

Coors in Colorado tastes better then the Coors shipped to California.

[Stuka]

cow: hope ya know that 258 takes a LOT more then 4 quarts of oil....

[CowKiller]

i know, but it can survive, with only 4 qts. trust me i know. it can run ok with 2 i found out.
thats how low it was when i got it.

[Stuka]

well it will "run" with no oil...just not for a long time :D
