I have a 1994 E350 motor home

Last fall it drove and shifted fine



Went to back it out of the shed last week end and it wouldn’t go into reverse



Ran it through all the gears a couple times and it finally went into reverse. I backed it out into the driveway It went into forward gears fine. But took several seconds to shift into reverse. Drove it down the road a couple miles to warm it up and it shifted into reverse fine



The next day we drove it 30 miles to get propane and it worked fine



Then we took it camping for a trip

It got down to 30 degrees When we went to leave it wouldn’t engage into drive or reverse



Cycled through the gears and it seemed to engage but it only moved 10 feet and stoped. Shifted through the gears again and it moved a few more feet. Shifted to second gear and it got moving. Shifted back to drive. Drove 40 miles home no issues



Got home let it set over night and the next morning. The same no going into forward or reverse After a few tries it worked great



The next after noon 70 degrees out fired up and shifted great



After searching everywhere on what it’s doing I realized that a couple times after it seemed to be worked shifting into reverse would kill the engine or lug the engine down until I had driven several miles



So it’s all temperature related

Is a valve hanging up in the tcc solenoid when it’s cold?



Pulled the codes tonight and none of them are transmission related



I am thinking it’s a faulty solenoid pack but hate to buy a $200 part if I am missing something

 

Most likely just hard lip seals in the transmission
My 94 takes a minute to engage, when cold starting, after sitting for a few days

 

i'm with above, dry lip seals, real world it would be best to do a trans OH. otherwise you will in the end tear up the clutch packs and do more damage

 

I have a Jeep that was having problems with hard shifting in the mornings. Did the suggested fluid changes and nothing seemed to work. I then came across a post that suggested using Lubegard additive. Ran it for about 3 months and the transmission shifts fine now.
Before doing an OH or replacing anything I would try Lubegard.

 

I agree
There are some pretty good additives out there that do swell the seals up some
They can help

 

always worth a try,
