Trailer towing ?????
« on: May 04, 2006, 08:01:00 pm »
I have a 87 Suburban( 1/2 ton 2WD) with a 350 and 700R4 trans i believe..I was told that you're not suppose to tow anything In overdrive(D) but in drive(3) so i wouldn't burn the trans....any truth to this...Thanks

ALWAYS tow out of OD. You will burn up the OD. The way I always pulled  my bosses sprint car trailer, ( 35' gooseneck Featherlight), is to get moving in D, then after up to cruising speed, above 55 or 60, then kick in the OD to save the fuel, but only on the interstate. NEVER leave the tranny in OD when you're in town towing with a load, the back and forth shifting from 3rd to 4th is what really kills em.

I concur.  No OD when pulling.  In fact, get yourself a transmission cooler for insurance.  You cant have too much prolonged heat to your transmission or you'll be replacing it.

Same thing with mountain driving, or 4 wheeling, etc.  Keep it out of OD.  That is not what it was designed for.

I put 110,000 miles on an'82 c30, 454, new 700r, pulling that 25,000 lb gooseneck. ALL of those miles were interstate running from Fl. to OH. and everywhere in between. OD off until the truck was up to about 60, then shift into OD. never had any tranny problems. Just fluid and filter changes every 15,000 miles.

We guys i made the First long distance tow with the suburban about 2 weeks ago( from chicago to Martin mi..150 miles one way) Trailering my race and she ran like a champ:D  No issues what so ever and i was hauling at a good clip to( 75-80 mph) at times. I did have a blowout on the trailer and had to buy a new tire:lol  But this 89 Suburban pulls well and we did tow in D until i hit 60 mph then we ran in OD....Thanks For the info.

Sounds great.  I hope you didn't have the blow out at 80 mph.

I would see what the tire says and what the truck recomends, then pick a happy medium that gives you a good feel while behind the wheel. I would lean closer to the tire recomended presure though.

Some people are like Slinkies. Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs

Whatever the tire pressure is rated at is what you should tow with. Some guys even go 5 psi higher .The tire rating is printed on the sidewall. Low air pressure is a killer while towing. It  causes heat buid-up and blowouts. Trust me  I know.
The addition of synthetic tranny fluid is another thing you can do for your tranny. It will not run as hot as regular tranny fluid.

There is no reason to switch screen names, you just have to tell me what your login issue is.  Did your read this post?  http://forum.73-87chevytrucks.com/smforum/index.php?topic=5300.0
