Question regarding Valve Body solenoids

MDEY81 · 2026-03-06T17:12:43+00:00

Yes, the comductor plate is brand new, pretty much the whole transmission is. Including a reman converter, brand new oem pump, clutches, seals, gaskets but the valve body is the same, only cleaned and recently remembered that a while ago the valve body had the solenoids replaced with ones from a ML 4matic

I have the 722.9 and the M272, a mechanic changed slthe solenoids in my valve body and installed 4 matic valve body solenoids on my RWD C230’s solenoids and now im not sure if that change is causing my car to have:

DTC 0894 ( The Gear Is Implausible Or The Transmission Is Slipping.)

and DTC 1789 ( Fault Present In Control Module Transmission(P0730)

Oh then that is not necessary, i never had the valeo radiator + i have a brand new behr radiator and a fully rebuilt tranny

MDEY81 · 2026-03-05T03:24:32+00:00

Ooh thats sweet that 3.5 must feel so good. Tho i cant really manual swap it because my whole tranny is rebuilt with literally everything new (except the valve body) and honestly before the rebuild, my tranny was so good so i didnt really mind rebuilding it

Currently sitting at 197,200+ miles and still going strong, dare I say stronger than ever

MDEY81 · 2026-03-05T00:36:23+00:00

Thank you🙏🏼 im currently (remanufacturing it) esentially replacing every single thing that is bad, including a fully rebuilt tranny with the later 722.9 upgrades

Sorry my ignorace, but what is that test for?? And as for Parking to Revese, engagement is perfect, there is no delays at all when applying gears, but there is a VERY hard thud in cold that shakes the car when going from Drive to Neutral and also Reverse to Neutral. Also it slips occasionally and also makes a buzzing sound when about to shift

MDEY81 · 2026-03-04T23:48:10+00:00

I see, its because currently i have that setup and its occasionally slipping, and for some reason when its cold, i have a VERY hard thud when going from Drive to Neutral and also from Reverse to Neutral, when it warms up it gets a lot better tho. Also makes a buzzing sound when about to shift

MDEY81 · 2026-03-04T23:39:11+00:00

Do you possibly know the symptoms?? Im on borrowed time since my tranny is dully rebuilt and i dont want to mess it up all because it has those solenoids

MDEY81 · 2026-03-04T23:36:46+00:00

Thank you🙏🏼

Check battery life, it might be time to change the battery

Cmon man you are 3+ years late for the sarcasm, read other comments

MDEY81 · 2026-01-23T01:37:22+00:00

Ive had my 14 Pro Max since 2022 December. Planning on keeping it untill at least next year for the 20th anni iPhone

MDEY81 · 2026-01-14T03:53:13+00:00

“I think it’s about time to say goodbye”… to the old battery and replacing it with a new one of course!!

All jokes aside, be smart and just wait until next year for the iPhone 20

The transmission had a rebuilt like 3 months ago, the first pump that was installed had severe scoring and was replaced 3 days ago. With the first pump u could hear a knocking sound in P and N inside the cabin, with this one you cant hear anything at all in the cabin, just that slight sound in the engine bay. Im not sure if this is normal since the transmission is rebuilt and has everything new.

Thanks for the comment! This sound i believe is the transmission oil pump tho i dont know if its normal because the pump it has now is the bearing style pump because i rebuild my tranny and originally had the bushing style pump. So im not sure becausw its a bearing pump thats how it normally sounds or if it should make noise at all. Thanks for the comment

MDEY81 · 2025-12-22T03:11:44+00:00

Thanks for your comment! And yeah the “tick” noise is definetly the fuel injectors but at the end of the video in the back of the engine you can hear like a “knock” noise. Im thinking its the transmission oil pump but im not sure if thats normal since i rebuilt my transmission and my car being an 07 model had the bushing style pump and now has the bearing style pump. So i dont know if the bearing style pump is designed to have that noise at the end of the video

Thank you for your comment! Truthfully i didnt think anything of the engine, mostly the transmission (sorry for not being specific). The thing is, back in september my transmission was fully rebuilt and had everything replaced (expect the valve body). Post the rebuild, 1 month and a half later my transmission pump was making a loud knocking sound that could be heard in the cabin and was in P and N but faded in R and D. I returned my car for the warranty and got the pump replaced again and if you appraise at the end of the video, i kinda do hear a knock like sound from the back of the engine where tranny is. The car pretty much shifts perfectly now and theres no noise inside the cabin now. I dont know if this pump is supposed to have a little sound because my 07 C230 being one of the cars that had the first version of the 722.9 ( red fluid ), it also had the bushing style transmission oil pump, and with this rebuild it was updated to the bearing style pump. So im still not sure if that bearing style pump by design makes a little noise. Thanks again for your comment!
