Torque Converter or Transmission?
Torque Converter or Transmission?
Hello All!
Recently my 88 dakota (3.9l, 2wd) has been shuddering/bouncing when taking off from a stop, stalling at redlights, & virtually no acceleration at all when first put in gear.
Sunday morning when going up a steep incline the acceleration became very slow and then finally gave out leaving me with a grinding noise and a no-moving truck. It will not engage in any gear at all.
The transmission was supposedly rebuilt 2 years ago which leaves me thinking that this is a failing torque converter. Am I correct in thinking this? If so, is it fairly easy to replace once the tranny is dropped?
Thanks!

When torque convertors fail they typically give up the ghost suddenly - then no go. I hate to say it, but I think the problem is elsewhere in your trans.
One possibility for your problem could be the flex plate to convertor connection. The torque convertor is held to the flex plate on the engine with 4 bolts. They can be seen through the inspection plate. If whomever installed your trans didn't properly tighten those bolts you may have lost one or two and sheared the remaining ones. That would cause the shaking/shuddering and explain the eventual failure to move.

I am going to take it to a transmission repair shop tomorrow to have them tell me what they think about it. I'll keep the thread posted.
Oh, not that it matters but it ended up being an a904 instead of a a998(which is what the spec tag said).
Well ended up being the tranny, whole thing is trashed. Not sure what I'm gonna do. Maybe try to find one at a junkyard or get real adventurous and try rebuilding it.
