has anybody had any trouble with there trans
makes a slipping sound and makes bang sound
towards the back of the truck after i let off the
gas and get back on the gas and sometimes
it acts likes it is 4 low when i back up and
go forward and it goes way it happens when
it cold or hot but mostly when is warmed up
and it is 4wheeldrive

 

First off why are you not a MD member?
Follow the link in my sigantureto become one.

Sounds like u-joints in the drive shaft 4 of them.
There are 2 in the center Cardin joint which is
a pain to do but easily doable in a home garage
but they are tricky.
Don't forget to put a line on the drive shaft before
you take it apart. If you don't it could run out of
balance and cause some real problems and if you
replace 1 replace them all.
Just mt 2 cents.

 

knowing which trans you have would help-does it do it in 2 wheel or just 4 wheel-kinda vague on your description

 

Also, how many miles on the truck?

 

just in 2wheel drive it has 47000miles

 

was a member but somebody removed me

 

any clue which trans ya got?aod-e4od-e.t.c?

 

well thats just wrong!!

 

4speed with od i think

 

that could be either one? the e4od had lots of problems in the earlier years-I would run a code scan and see if ya get any stored codes-some trans are electronic controlled and one small glitch will make them act up something terrible-and some act up just slightly low on fluid

 

I think it sounds more like universal joints rather than tranny....like Dave said up above. Crawl under truck while in park, engine off. Grab driveshaft and twist....see if there's a lot of play twisting one direction, then the other. Refer to Dave's post up the page a bit.

 

you know Bud sometimes it is best to block front wheels raise rear of truck and put in neutral so the shaft can be spun-if they are in a bind you can't feel the play at times-just for future reference I have had that problem before

 

Also, just "looking" at them (if they are that bad) you can see that there are toast!
