Case 2090 will not move in 1st power shift

I have owned this Case 2090 for over 25 years. Well under 3000 hours. I put a new cab kit in it mid winter. Drove it to town for a good cab washing at the car wash after the old interior was taken out. Tractor shifted perfectly to and from town and all fall as well. It pretty much sat in the machine shed all winter with no use. I did start it a time or two. Went to take it out of the machine shed the week before last and it will not move in power shift #1. You can bump it to power shift #2 after the clutch is let out and it move just fine. When you push the clutch in it will "grunt" as normal. I noticed that when the clutch is engaged the 3 point hitch will not lift. When you push the clutch in the 3 point will come up. I don't think reverse works properly either. Is there something simple I am missing here, or does the tractor probably need to be split. My mechanic says that some bolts have probably come loose causing a clutch pack to not pressurize. He also said I might have some cracked tubes that feed pressurized hydraulic oil inside to the clutch pack. Mentioned I might have a blown gasket under the valve assembly, but that is rare. I did change the hydraulic filters and check/add some oil. Anyone have this type of experience? I did post on the J.I. Case forum without any replies, so I will post here. Thanks for any help.

Surely there?s a case guy that has an idea

I've never been around nor driven any case tractor newer than the 30 series. I'll go out on a limb here, and guess you may have something. That getting it wet from the power washing this past winter, may have caused a bad connection or, rusted something like a cable that controls your shifting.

The case guys are busy planting now, they will get to you. Ask for 1370rod. He's the best. But I suspect your mechanic is correct and a tractor split is in order. When a clutch pack goes bad you loose all the oil which is why the 3pt doesn't raise. But I'm certainly no expert on that.

I went back and looked and your post is back on page 3 on the case forum, try reposting it today and I'll send Rod a msg about it. I know he's been trying to get finished with his crops

You need to hook up to all 4 clutch packs plus plus lube circuit on the powershift valve.It is on the right side of transmission. You really should have 5 400psi gauges. There is 5 pipe plugs 1/8th pipe threads. It does sound like you may have a leak in c2 clutch It also sound like your mechanic has some knowledge of this power shift transmission. Let him help you.

Marlins advice is a good idea, sure sounds like a possible leak, but the test is the best place to start. Rod.

Marlon/Rod just for my own knowledge does a 2090 have issues with the clutch pack bolts breaking like a 1070? My understanding was that they upgraded newer models to get away from that problem.
