1999 mercedes 722.6
Question, This car delays when cold in drive, it kinda acts like its low on fluid but its full(i have the tool to check the fluid)When the car is hot you would never know there is a problem, it works nice, seems only after it sits a few hours. Thoughts on this please, (drainback maybe?) The wholesale account this came from put a radiator in the car, could he have left something out causing drainback? Thanks

At least you know it is not a fluid level issue or drain back issue. Probably best to start with an RDI and see what yo find in there.

Hello,
Got the trans out, nothing really jumps out at me to say i found the problem, some orings seem alittle flat but other than that i dont see too much. This also has the scarf cut rings so i will be updating those. Any other suggestions would be great. Thanks Gary

Make sure you replace both sprag elements. Check the VB for a broken pressure spring, common on early units.

Thanks Pat,
I checked the spring, that was good but i will be replacing that as well as the sprags. Pat, The molded piston in the pump area and the plate(sits inbetween the stator abd bell) do you replace those items on every overhaul? Thanks Gary

Yes, I usually replace those. There have been times when I didn't, but they are not that expensive.
The plate usually comes with the kit. There 2 different height molded pistons. The only difference in apply elements between drive, 1st gear, and reverse, is the B2 brake (clutch). That is where I suspect your problem is.

It always sucks when you can't see anything in there.
But since reverse worked fine, and it did it only cold, you know it has to be a sprag or a seal somewhere so I like Pat's advice on this one.
