Default Only God can help me now - 08-30-2018, 11:11 AM

looking for some help from anyone who is willing to listen to my story,

almost a week ago i was driving to the bank (about 1/2 mile from my house) unfortunately while i pulled into the bank, i hit the curb. shattering a coolant hose. allright, no biggie, i wait for the car to cool all the way off before trying to move it. i made it about 50 feet before steam started bellowing out of my car.
i pull over again and wait for my friend to tow me the couple blocks to my house. the car cools off, and i am towed by my friend to my house. and drive my car from the base of my driveway into the garage, no problem. i end up fixing the coolant line and start the car again. the car starts perfect but as i engage into reverse, no engagement (automatic) it just revs out. i quickly get a transmission fault error so i shut off the car and push it back into the garage with the help of my roommate.

i jack the car up and notice the trans oil cooler line has a hole in it and my belt is shredded. after several days of pulling the car apart to replace the belt and trans cooler, I finally get everything put back together. i start the car and the most horrendous squealing noise comes from the engine bay, accompanied by a pretty low idle. ( remember the car started and ran fine with the exception of the tranny and leaking oil) i'm not sure what the problem is, or why its squealing so bad.
i assume the reason it wouldn't engage into gear is because of the transmission oil cooler being broken? i'm not sure. any insight will be greatly appreciated.
ciao!

Make sure no belt fragments got sucked into the crank area around the main pulley (search for info about that). The squealing may just be a problem with the belt installation. Did you also replace and check the tensioner? Did the pulley get loosened somehow?

Any pics?

thanks for the reply, yes i did replace the tensioner because the bonehead that owned the car before me stripped out the t-60 socket (i assume they tried to use a hex bit) i have it installed correctly as well as the belt. if i'm going to take off the main pulley, should i maybe open up the timing housing? thanks

Damn, what kind of curb hit will break coolant hoses and trans coolers??

Double-check there's no remaining debris around the pulleys. Look up info on the trans going into 'safe' mode if it detects low fluid, assuming a lot or all of yours leaked out from trans cooler.

yes i can get a video uploaded later today, ill have to figure out what type of trans fluid i need to buy since bmw is so picky. i did however, use the blue BMW coolant for the refill. i think the main reason this became a problem is because i didn't have the belly pan on the car when i hit the curb. but i will get a video up here in a little while

Get the Pentosin transmission fluid, it will save you a ton and it'S what the oem stuff is.

Just want to hear the noises

Why not make an insurance claim at this point and let someone fix it for you, pending you have the right coverage on it.

check your powersteering pump pulley. They are notorious for commoing into contact with the subframe after a major jolt like that . thats where i would put my money.

Any update?

Did you refill the transmission fluid and bleed it? If it it's a DCT, fluid level is critical.

Also if any fluids got on the belts, you need to clean all the pulleys and the belt, to stop belt noise.
