UPDATE: TESTS ON PAGE 2



While recently off-roading with my '07 Sahara with an auto transmission, I was attempting to climb a steep flat face incline. I bottomed out/high centered at the top and after several attempts and many tranny skid plate scratches/dents, I gave up. Yes, I was the p**sy for the rest of the day, but I stopped because I was afraid of starving the trans pump of oil.

So in short, here's my question:
What incline/decline is safe for the automatic transmission and for how long with out worrying about starving it for oil?

Secondary question:
What can I do (other than a rip apart and rebuild) to help beef the trans up for 4x4ing?

THANKS!

REALLY? No one has any advice?

I dont think really anyone knows...this is the first time I have even heard of this. Would like to know as well since I have a automatic.

Do some experimenting. Drive onto a steep incline and check the dip stick. The fluid intake is very close to the bottom of the pan. Fluid level is way above the pan parting line.

The best thing you can do to "beef up" the automatic transmission, is beef up the cooling.
An aux cooler, maybe even with a fan for those slow hot days.

On my last outing at Rowher Flats, which has several very steep inclines, my "Hot Oil" light for the transmission came on. Luckily, there were two guys following us on the trail, who just happen to be transmission mechanics, told us to keep the vehicle running in 4lo with the air conditioning running. The "Hot Oil" light never came back the rest of the day.

Don't over heat and most of all don't over fill and don't go alone

i have done some pretty steep but short climps and never had any problems. i have heard of people loosing drive though while climbiing. Look in Rock Krawlers heavy duty deep trany pan. Supposed to be beefy as hell and help prevent trans from running dry.

Hi ARM2004

the problem with deep trany pan is clearance for the skid plate,back in the old days lets say 50's 60's we used to carry the old water bag, that we hung from the rad cap, it was made to drip water down the front of the rad, young people wont know about that today

Out here on the west coast we have very hot and dry heat with little to no humidity to carry the heat away and some very long steep grades on the freeways some are 20 to 50 miles long or longer.

Had an engineering professor in 1978 whose brother owned a 'vette that would overheat during the summer months. The solution was to reroute the A/C coil condensation drain to just in front of the radiator, that small drip was enough to solve the problem.

I remember asking my dad about those bags when my parents and I took driving vacation in 1964 through AZ and NV. Oh hell just realized at 54 I guess I don't count as young people any more.
