After I drove my car to the gym last night, i worked out then got back in it put it in reverse and when i hit the gas the tranny was slipping like crazy. I had to rev it to like 2000 rpms for it to move. Is this normal (doubt it) or do i need new clutch plates. O yea its an automatic

 

This could be a number of things, easiest thing, is the e-brake on? Next check the tranny fluid level, it probably is low. (check while engine is hot and running) or possibly needs re-build. How many miles? which engine?

 

Rear or front band is shot Not sure which one but maybe that. Does this happen in Drive?

 

...model truck be nice year even better

 

could be numerous things, does she slip in drive too?.. if thats the case i would rule torque converter, but if shes fine in drive, eithershes slipping from shot clutch packs or a bad band, eitherway, the transmission is gonna drop dead soon from all the particulate being stewed up inside the slush box (automatic transmission)

 

well it is a 2000 4.7l with 115k miles on it. The weird thing though is that it only does it like evry couple of weeks maybe. And it only generally happens when i am backing out of a parking space or something like that.

 

My guess torque converter not engaging properly. With it that new, not sure what else would cause that. Maybe your missing some oil? Check the tranny fluid, in neutral. Believe me iv dealt with my tranny enough, and it's a pain. Might just be not enough fluid and takes a bit to get to the torque converter...

 

i would rule out the torque converter the cause of the problem, sorry varsis ... sounds like something is slipping in the reverse system, band, clutch pack or the fluid pressure to control that is weak, either way, i would have her inspected by a reputable transmission shop, stay away from any dealerships, they will immediately throw you some mumbo jumbo that the transmission is copletely shot and your going to need a rebuild or a reman... enjoy <-- sarcasm

 

I wouldn't Rule it out. The rear band I believe or front either or, Controls both 1st Gear drive, and Reverse. Which is why I would believe this, but it could be anything else too.

 

once a torque converter calls it quit, with my experience of failling torque converters, once their stall speed begins to increase above the speed they were designed to operate at, it just will progress worse and worse, you can annihilate a thrust washer inside it and the converter will still continue to run fin, but dump a ton of brass particles into the transmission, then ripping apart the clutch packs and clogging up the valve body... chaos
