no power in reverse

ok i have been told that a ford 4.9 (300 straight 6cyl ) will pull a house down, lots ot pulling power: this is what i have heard from a lot of true blue oval owners say and even that forigen vechile owners say ( chevy people ),, that the ford 6 cyl has house pulling power and torque,, i have replaced my clutch once already. but it still has no balls while towing something in reverse, meaning when ever i am hooked up to either my boat ( about 2g`s in weight ) or my camper ( 5,500# ) when i put it in reverse i lose all torque in motor for pushing it. but towing it forwards i have no problem what so ever..
now it has a brand new clutch and pressure plate, release bearing, pilot bearing and clutch, master cyl. hydraulic line to centrific slave cly. ( has no mechanical linkage )..
and was told that my catalic converters can be clogged,.
taking a chance and replacing them tommorow. and was also told that since i didnt have flywheel resurfaced ( looked in good shape ) didnt think it needed resurfaced,, that that can cause my no power in reverse and causing me to smoke the clutch in reverse while trying to back up ..
this is in a 1989 fullsize broncoxlt with about 92-93,000 actule miles with a 5 spd tranny,,
now i know a 6cly doesnt compare to a 8cly but for total spent on purchase and new shocks on all 4 corners along with new brakes all the way around along with caipers, rubber brake lines and wheel cyl total spent was less then 1,500 and truck has excelent intior and needs only 4 holes patched,, and i add a bottle of berryman injector cleaner with every oil change.. every 3,500 miles tune ups every 6,500 miles
any help will be greatly appercited,, thnx blackbroncoxlt

Re: no power in reverse

Yep, thinking the same thing about the hydraulic "surge" brakes.
There should be an "override" lever to engage in order to back up.
Dad blew up a C6 years ago trying to back our boat into it's parking spot, up a hill.
Once we found out how to override the brakes, there was no problem.
This particular trailer had a lever you pulled up, and put a 2"X2" underneath it to disengage the brakes.

Re: no power in reverse

I used to be surprised how many boat owners didn't know about the reverse override...now it's just normal to show them. Even people who've had trailers for years still try to power them up into their driveways.

Re: no power in reverse

I would have to say BP and WD are in the know. The ONLY other thing I can possibly imagine is the fact that the 1st gear forward and reverse gear I'm sure are numerically different. If the reverse is numerically lower, you will have less power, but there should not be too noticeable of a difference, so, see comments above.

Reverse override

It should be on all "surge" type trailer brakes.
Those are the one's that operate mechanically vs. electrically.
When you hit the brakes going down the road, there's a hydraulic system that will sense that, and apply the trailer brakes.
In a nutshell, as the trailer trys to "push" the braking vehicle, the coupling will slide forward towards the vehicle and the trailer brakes will engage.
If you try to back a trailer equipped with "surge" brakes up a hill, or even on flat ground,
it will push the trailer into the vehicle causing the brakes to engage.
That's the situation that the override will eliminate.[img]images/icons/wink.gif[/img]

However, you also posted those type brakes are not on either trailer.[img]images/icons/crazy.gif[/img]
Maybe <font color=blue>TheJuice</font color=blue> made a good point about the gear ratios.
Reverse should be low enough though.

Let\'s step back a moment...

You said you replaced the clutch, so obviously you have a manual transmission - what exactly happens when you notice this "lack of power in reverse"????? Does the engine rev up, but the truck &amp; trailer don't move? Does the engine stall? Does the engine lug down, but neither stall NOR move the trailer? Or does the engine rev up &amp; move the trailer but not very fast? Be very specific and thorough in you description.
