Trans question please help

Ok I'm new at all this, just purchased a 99 winnebago adventure and I Had a problem with the transmission but with a lot of searching on this forum I was able to find the fix for the problem that I was having, this unit is a ford f53 chasi and its got the v10 and I did a ground cable update for the control mudle and its working great but once in a wile the trans shifts a little bit hard from first to second and to third, not always its usualy smoth but some times just feels a bit to hard, do you guys have a idea what could be or is it normal? And if guys have the experience with this unit what tire pressure should I run, the winnebago stiker says 70psi does that sound good? I would like to make it more quit in side wile driving if I drop the tire pressure will it help? Thank you all, Joe.

Can not help you with the Ford Tranny. but tire pressure I can

There are two tire pressures all but guaranteed to be WRONG for your rig
One is on the sticker inside (it is the proper pressure for the rig.. EMPTY, of course the instant you step into the rig, it's wrong)

The other is stamped on the tire and most folks do not read it properly either, it does not say "max Pressure" it says "Max Load of XXXXX at max pressure of YY"

The proper pressure is found by going here http://www.rvsafety.com and having them weigh the rig, they will then tell you what pressure to use in the tires (I edited the link Thanks RVdude, you beat me to it as I was checking to make sure and due to a slow connection it took a while)

Mine run 115 psi for the most part

NOTE: each wheel may be different (inner and outer tires are the same though)

Home is where I park it!

wa8's link is incorrect, that link should be http://www.rvsafety.com/

A second best to individual wheel weighing is a truck scale at a truck stop for $7 or so which gets you a total axle weight for each axle. Once you have your fully loaded fully wet axle weights go to the tire manufacturer's web site and look up the tire inflation tables for your tire. The axle weight divided by 2 and generously rounded up will get you close enough to the individual front tire loading and if you have duallys on the rear the rear axle total weight is divided by four and generously rounded up. The tire table will then tell you what to inflate to based on the weight carried.

Read what the sticker says - it should state both a pressure and a load that pressure will support. Normally the sticker will show the pressure required for the maximum axle load (GAWR). That is likely to be a pretty good number for the rear axle but high for the front, which is usually under-loaded.
