@TheMinuteMasters well I did a converter once didn't check how the seal wood fit the torque converter after all the work I did on it when I started the car had a massive leak after redoing everything turns out they sold me the wrong seal ever since that incident when ever I have to replace this particular seal I first check seal to torque for proper fitment before install never had that issue ever again
Isn’t there a large o-ring and flat surface gasket around the pump that also shrinks and leaks with age? Did you replace the o-ring? Experience says reseal everything with new once you have transmission out. My 2 cents.
You are correct. I didn’t change the gasket between the pump and the bell housing because I didn’t want to get that far into this repair. I also didn’t think it was leaking. This transmission needs to be rebuilt anyway.
Most of the time it's the bushing behind the seal is what's causing the leak I have figured out the hard way to replace them both and not just the seal
It looks like you have the channel side of the seal facing away from the transmission? I'm not a transmission expert, but I usually see the seal channel pointed toward the transmission.
If you were looking to replace the torque converter seal shop may charge you between $700 and $1000. If you do it yourself, it’s just the cost of the part.👌
@@TheMinuteMasters thank you , im sure this seal is broken or bad on my 08 f150 it basically pissed trans fluid the other day and it didnt want to drive anymore , how much would this repair cost on average if i go to a shop!
Good question! It’s been away since a pulled a C6 but I’m sure it’s similar. If I understand this correctly, the AOD, 40DE, and 4R70w are basically C6 transmissions with overdrive, slightly different gear ratios, and some electronics.
