:
help i have a 1989 302 bronco and i need to know the towing capacity. i don't know how to figure this out. i just bought an rv weighing 5400 , i've been told that i can pull 6000 lbs or so but i don't want to damage the tranny or engine, 302 with 35,000 miles on replaced engine. the owners manuel does't say just refers me to the rv towing guide and something about figuring the gcvwr??????? anyone know the answer. i don't want to get another truck and i don't want to finalize the travel trailer sale until i know. thanks sharon_d

 

Buy an owner's manual.

GCVW = Gross Combined Vehicle Weight, you should have a sticker on the drivers-side door post that has what the truck GCVW is to figure what you have look on your registration or the door post for the vehicle weight and add what the trailer weight is and you will have the GCVW. My only suggestion would be no matter what if you are going to tow a lot be sure to get a tranny cooler this will save your tranny this probably the most important single thing you can do to help in towing. IMHO I think you will be fine pulling the RV. Hope this helps and Good Luck,

Well, it all depends on which tranny is behind your 302,and what the factory axle ratio(s) are.A 302/5-speed/3.55 gearing combination was given a 4,000 lb. rating.A 302/AOD/3.55 combination was given a 7,700 lb. rating.The 302/AOD/4.10 was given a 8,000 lb. rating. The manual rating was lower due to warranty concerns(owner's needing the clutch replaced from a lot of wear), that dealerships just didn't want to deal with(no pun intended....)often.You can find out what ratio your '89 Bronco came with from the factory by looking at the data sticker inside the driver's side door jam.Most likely you'll have an "H9" under axle code.This is a 3.55:1 with a rear limited-slip.An open 3.55:1 would be "19".The optional 4.10:1 will be an "H5"(rear limited-slip).The only way your Bronco could get the steeper 4.10:1 gears is with the 302/AOD.Some 302 Broncos received the C-6,three-speed automatic,but that was a running change from mid-1990 models to a R.P.O. for 1991,so if your 302 has an automatic behind it,it's the AOD.Tranny codes for 1989 Broncos are :

K=C-6
T=AOD
M=5-speed
Z=HD 5-speed
F= 4-speed

Hope this helps.
