torque converter or tranny?

[carnuck]

Either the high forward clutches burned out or if they are still good, the drum seal popped. I used to replace those seals for trans shops that didn't have the tool back in the day.

Something that hasn't been asked yet...does SleepsUnderCar's Concord have a Chrysler transmission? Everything I have on TorqueFlites says if the transmission slips in 3rd it's likely it's going to slip in reverse also. The rear clutch is applied in all forward ranges, so I think it's OK. SleepsUnderCars says reverse is fine, but the front clutch is applied (with the rear band) in reverse and 3rd (with the rear clutch). So now I'm confused and left to wondering if we're even talking about a TorqueFlite.

The high forward clutches are engaged in drive (3rd only) and reverse. First gear can still work with bad rear clutches because of the one way sprague which takes the load off them, but it doesn't work in reverse so reverse wouldn't work if they were bad.

yes, it is a Chrysler 904.
i have done some reading up on this, the best article i found seems to point to the front clutch pack. the one thats only applied in 3rd and reverse. yes, reverse works...for now. what i have read says i can expect that to go out soon. i am probably just going to park the car until spring, i found a cheap winter beater to use for my commute to work now.

It is possible there is a clog in the valvebody keeping it from going into drive. . If the passing gear valve was jammed, it would rev fairly high before going into second from first.

PS: It's a 998 (related to 904, but with bigger rear band) and probably a lockup

If it's a Spirit, (as mentioned in the first post), it IS most likely a 904. : )

Sorry, but no. 904 wasn't used after '79 on the 6 cyls. They were snapping rear bands before warranty was up.

<----PS: Ex-Mopar trans tech, back when Hemis were still available.

According to my service manual, 1981 6 cylinder Spirits/Concords came with 904s.

Since they look the same to most casual observers, it's not a biggie. The case has a couple ribs where the wider rear band lives inside to tell them apart.

[SleepsUnderCars]

it's a 1980 spirit ith an Iron Duke. 904.

Shows a 998 out of an Eagle. The 2 ribs on the side aren't on a 904.
