Transmission Slipping on Steep Hill

1995 Thunderbird - 280K Miles - Original Transmission - Serviced within the last 20000 miles/18 Months - Fluid flush

Transmission slips (Like Neutral) when leaving grage on very steep hill - Generally will re-enage if you let off the gas and try again. Does not heppen any other time. Transmission works well in all other conditions. Checked Fluid and it's full.

Any thoughts on cause of problem

The early trans has a flat pan, which on steep angles can allow it to suck air. The fix is to replace the pan and filter with one for a 96+ 4R70, which has a sump in the center that the filter picks up fluid from.

-91 Cougar LS, coming soon, complete overhaul with a 427" Windsor.
-90 XR7 5-speed black on black w/sunroof, MP2, coated rotors, double intercooler, 15%OD, ported heads, comp stage 1 cam, 85mm TB, 90MM LMAF, 80# injectors, and ported big valve heads
-98 Mark VIII LSC, Procharger P600b, TR3650 swap and 3.73s.
-90 SC Automatic rustbucket winter beater
-97 Tbird Sport 4.6 Nice weather daily driver

Thanks - That sounds like that's very likely it - As you might suspect the transmission shop was ready to sell me a rebuilt transmission!

FWIW, I've bought those 96+ pans for about $24 at the Ford stealership.

I happened to try and grab one from Pick-N-Pull while I was there and they wanted $30 for it!
I told them I can get one for a little more than $20 brand new, but they don't care (bunch of ripoffs).
