Probably the most informative video I've ever wached about zf8hp 😃 great job!

What's mostly the reason behind 2-3 hard upshift in these transmissions although the ATF is clean and well maintained?

[alrui]

You mention the "bonded" retainer. Does the term bonded mean with adhesive or press fit or simply the tab?

[alrui]

Any links for the Transtec seal kit upgrade thats mentioned?

Who do you guys get your parts for rebuilding ZF 8HP70?

I have a problem with my Chrysler transmission. If I start the vehicle and I do not engage reverse immediately the reverse (R) flashes and asks to return to park, also while driving 1st, 2nd, 3rd shifts perfectly then I have to get the RMP up to 2G for it to shift to 4th gear, then all the other gears shift perfectly. Is this a complete transmission problem or a bad valve body/ TCM issue?

I am having issues with my 8hp70 and I am out of warranty. When I come to a stop, sometimes it almost feels like I get a slight nudge from something in the Driveline. Also, early in the morning, my 1 to 2 shift is extremely long and harsh when it finally shifts. There is also a shutter from the 2 to 3 shift at times. It seems to act better once it is warmed up, but there are still weird corks about it. I've had a lot of bad experiences with dealerships and shops in the past and was wondering if there was any diagnosis that I could personally do before taking it in to verify what the problem might be.

Is it necessary to "reflash" the ZF 850re transmission after a trans flush?
