I guess I don’t need reverse any longer

[RST Dana]

First oddity, I was driving normal after exiting I71 today to purchase fuel. Moving about 20 mph, the engine starting reving as if it was downshifting (I did not have the fast pedal pressed more than needed for that speed). I let off and reapplied the horsepower only to feel as if the TQ was slipping a tad. Hmm Topped off the tank and tried reverse on restart, no bueno! As I entered the rap the CEL appears and I was able ton reach 60 mph, at 3800rpms. Dropped it off at my dealer and I will call Monday to check the status of a loaner of my 116k trans issue. Lifetime powertrain warranty is about to get tested!

Is that one of the transmissions that GM is being sued for?
Man, I really love my GMT800.

It is the 10 speed we all love! Or I used to anyway….

What year is this truck? Do you tow heavy with it?

I’ve had trans issues before in a f150 but I was routinely towing 8000lbs. Went through 2 trans and I junked it before buying the 3rd.


I tow with my 2026 and just take it easy!

No towing, no big launches either. Just a sweet 21 HC hauling people.

Shouldn’t have failed! Good luck with the repair. Are they going to get you a new trans or a rebuilt trans? Just curious.

I don't think the 10 speed would survive me, not unless it can be beefed up.

@NickTransmissions any change you have a non problematic valve body for a 2022 10speed GM24071207

@NickTransmissions said he hasn't started building those yet.

Transmission shudder - what about it?

About 6 months ago I traded my 2015 LT for a 21 LT. About 150K miles were on the 15 model, and the 21 has about 92K now. After about 1K miles I started to noticed some stuttering (washboard sound/feel) and took it to a shop. They determined a transmission fluid flush with filter, and said if it...

Sorry, been slammed with work in the shop as of late so haven't been online as much.

I don't have any 10-speed valve bodies...I've been trying to acquire a couple 10-speed cores to learn on but it's been extremely difficult as GM is charging over $3,000 for just a core. So no one is not turning them back in...Both GM and Ford have had major supply chain disruptions when it comes to parts like valve bodies, drums and entire complete transmissions. A few of my customers who also own late model trucks equipped w/10 speeds have had them stuck at the dealerships for weeks to months awaiting warranty replacement parts....
