check this out, it may be helpful, I hope.

model number and type would help. top freezer? side by side? etc. If refrigerator otherwise working good, buy the icemaker KIT from homedepot.com or lowes. should include solenoids, and complete icemaker. type in appliance repair in the home depot search engine. should not be much over $125.

How does it work when cold? Like normal? Or are there problems or slippage then too.
As the engine warms up, so does the transmission. As the temp. rises, so does resistance in things like shift solenoids, lock up solenoids, etc. This makes it harder for the computer to make the solenoids work so, this could be the problem. You should have some sort of trouble codes associated with that type of failure. If you have no codes, it may be mechanical. Possibly clutches worn out.
I hope this helps you out.
Good Luck!!!

Very common problem. The solenoids when cold will sometime work once then get hot and fail. Replace the coils. I made a short video which shows how it works and how to replace the coils on a similar dryer with the same type of solenoids:

The shift solenoids can be changed on some models of transmissions. Check your connector plug for corroded pins first.
I do not have a link to the site you want, but I can tell you there are some pictures and videos showing the shift solenoids and explaining removal. Some are tight and close to the frame, but not impossible to maneuver.
The videos I am referring to may help you determine which solenoid represents which gear. Do a Web search of your transmission type and cross reference it with shift solenoid repair.

depends on trans type.
4R70W- in trans pan, they are the 2 solenoids together, silver in color held in with 2 8mm bolts
E4OD-- also in pan, but it is a block of solenoids held in with 8 or 10 torx (30) bolts

The flush is something you never want to do,
as you found out

You may have sediment in the shift solenoids,
from however the flushing was done

Your only hope will be an honest trans shop,
to work on the problem

Sounds like the shift solenoids. A common problem, but before fixing that, try swapping the fluid with Multi-Vehicle type fluid. That transmission, mine included, seems to work better. If no improvement, then shift solenoids
