48RE Trans slipping on incline
Truck has 100K 3 trans oil/filter changes. When towing buddies 15K boat out on 35/40 degree incline in 4 Hi the truck would barley move and the rps went very high until it would move. We had to put it back in the water to reset boat on trailer and I tried 4 Lo and it walked the boat right out. What gives?

I think it has to do with the stall speed of our crappy torque converters. I have had similar results with my 5th wheel (only about 10k) when putting it away in my driveway going up curbs, etc. when in HI. Now, I simply pop it into 4LO and it doesn't even blink at moving it over anything.

FYI my torque converter started leaking ( not slipping) so I pulled the trigger on a Goerend transmission just before June this year. The it was like a new truck now except it has 102k on the ticker. The transmission knows exactly what to do even downhill w/cruise doesn't surge. The torque converter was going to cost around $1000 and the tranny was $4800 but 3yr 100,000 mile warranty. Nothing worse than a wimpy transmission. Just thought I would throw it out for you.

I would assume just like your truck does now in 4Hi. It would rev up and slowly get the load moving. Obviously gear ratio will play a roll too. 4.10's will pull it out better than 3.73's. I feel the biggest issue is the stock convertor slips alot. My brother's truck is identical to mine except he has a built trans with triple disk convertor and he pulls the boat out in 2 Hi alot better than mine. Our ramp in Ocean City Maryland is steep....almost all boat owners with 10K and up boats use 4 Lo if they have it. You can definitly tell when Nick is hooked to her in 2 Hi with his 5 inch MBRP exhaust.....very loud.
