overfilling fluids?

[sly]

It is unpossible to make a gear box "explode" by over filling it... You will however push fluid out of the seals... Whether you are dealing with an automatic or standard transmission you will fail your seals by overfilling it. Aerated ATF can cause your tranny to build heat and fail also...

it is a story passed through my dad... so there may have been some embellishment.

I do know for a fact (multiple witnesses - about 10 confirmed) that my uncle had his trans blow into the passenger floorboard. The planetary exploded and sent crap about 2 o'clock looking at the tail-shaft. He was really lucky that it didn't shred out at 10-11 o'clock. That one required much body work (floor) and a new trans. Dunno what caused that one though. That part was never discussed. Knowing my uncle... probably lack of fluid.

I was in the car when my Dad blew the tailhousing apart on his toploader 4-speed (69 Mercury Cyclone GT 351W 4V). Low fluid from a blown seal caused that one. I looked behind the car and saw the cast iron chunks bouncing down the highway.
Catastrophic failure in an automatic can kill people as can a flywheel failure. That is why you are required by the NHRA to have a certified transmission blanket depending on ET for an automatic and a certified bellhousing and flywheel for a stick.

Yeah. My uncle broke the bellhousing on a th350. Shifted into 2nd at 7500 and heard this awful noise, and a very wierd feeling in the in the car. So we stopped and got out to look and the bellhousing had split all the way around, so it seperated it's self from the tranny. It was pretty crazy.

lots of torque does funny things to metal. I know a guy who did that to an AOD behind a 347.

hey guys once again , i know its an old thread, but its been a while since i changed fluid in a panther, i change dthe oil, now when i loo at the dipstick the oil goes past the crosshatched area area into the arrow area its a 1/4 inch below the f in FULL,is that fine???

[sly]

if you have a box... and you drained both parts of the pan (2 plugs), changed the filter... and put 5 quarts in... then yes. If you missed a step somewhere... that's why you have over much.

That's fine, a touch over in the oil department won't hurt a thing.

[gadget73]

the dipsticks weren't always accurate from the factory. If you drained both plugs and put in 5 quarts with the filter, just mark wherever it lands as the full mark.

[porschpow]

well i drained everything.....both plugs and filter

i bought valvoline 5.1 quart bottle and a quart of lucas,

i poured a little about 3 quarts of valvoline and a quart of the lucas and added a quartish of valvoline on top of that

its like a quarter inch below the F in full and a little above the crosshatched area

[pantera77]

Next time save yourself $15 and don't waste the money on the Lucas.

[porschpow]

See, my problem is i should've done the new mark before I went through this oil change. I now have to wait until next time or let some oil out. I don't know

I think I have a little more than 5 quarts in there cause I still have 3/4 or a quart still left in a bottle

Haven't really experienced frothing from the oil dipstick,

what about frothing from the tranny dipstick?

transmission fluid = death

power steering fluid = red spraying death

engine oil - read around here about 5.0 dipsticks reading incorrectly. you put exactly 5 quarts in at your next oil change, let your car sit long enough for the oil to drain back to the sump, then check your dipstick (all on flat ground btw), that is your full mark.

foaming/frothing can happen when the engine oil level is too high, as well. you don't want that.

granted, there IS a coolant overflow reservoir, but it's there because coolant expands

I guess your not a big fan of lucas, why? You are the first person to say anything against Lucas

[sly]

It's a bandaid and it's not really needed if the car is running right. The only thing I've ever seen that really works is Auto-RX (buddy used it on his 300K mile T100) for removing the sludge from the engine. Worked like a champ, but you have to follow the directions exactly. and you WILL go through some quick oil changes (first at 500 miles after application). And the oil filter will be chock full of crap too if you have much buildup.

back on the oil change subject. No worries if you have half a quart too much in there. you're not really testing the limits at that point and the engine will use that much before long anyhow.... so look at it as saving you a top-off mid change.

[porschpow]

Gotcha, I will consider that Auto-RX although that would probably test the limits of the sump (clog it up). Other than that it is not a bad idea

Back on Lucas, my brother had an 87 MGM that had a substantial knock on it. He putLucas in his car and it lasted him 2 years with that knock and still ran till the day it went to the junkyard

As for the oil thing, I was going to leave it alone (originally I was going to crack the front oil plug and drain a little oil out of it)

[sly]

auto RX is a slow process sludge remover. I think they guarantee not to clog the sump. I'll have to double check. Hence the reason it takes 500 miles to gunk the oil filter. But it's very effective. it's a 2-pass system. 2000 miles, then 3K. Then back to your regularly scheduled interval. My buddy did one at 500miles to avoid the feared clogged filter. Wasn't that bad according to his posts.
