I have a '91 Pickup, 3.0L V6, A340H A/T, 4WD. It seems to be experiencing transmission trouble. When accelerating from a complete stop the engine revs but the truck just doesnt want to go. I have done a tune-up, and tried to retrieve codes but everything came up normal. I am considering a transmission rebuild. I have worked on A/T before, however im not sure about the rebuild kits, and whether or not they replace the components necessary to help with my problem. Is there anything else I can do? and would a master rebuild kit or master clutch kit even work?

 

Is this while being cold?

Does this happen only after warmup?

Does this happen accelerating up hills?

 

warm, cold, up-hill, flat-land, doesnt matter.... it seems to happen less in the higher gears... on the freeway, or just 45 and up.... driving around town it gets bad tho.... and its eating gas

 

Blackie was experiencing (what it sounds like) the same troubles... ended up being the combo of a clogged fuel filter and a bad AFM...

Best of luck to you!

 

sounds like torque convertor slip, first check to see if your full od atf, then if you are and still slipping im guessin its time for a new one. make sure its not just your torque convertor before you go putting in a new tranny, im not sure how to tell someone else will though.

 

fuel filter was one of my first thoughts... put on a new one when i first started having the problem a year ago

 

its ok on fluids... not leaking anywhere... just burning gas bad..... im getting like 12mpg on the highway

 

3.0 with how many miles?
They are not exactly knowN for great mpg's

 

149,000

 

im online now trying to figure out the location of the torque converter... if anyone can help me out with a link or diagram? im not really finding anything....

 

In between the transmission and engine, hidden in the bell housing.

 

how does a fuel filter or a maf translate to a slipping transmission?

 

i think what he was trying to state is when he hammers the gas you get alot of rev and noise with no go

 

exactly!!!

 

just pull the trans and replace with a 5 speed.

 

One would think that'd be more expensive (and more time consuming) than fixing the problem and although it's a great idea for a swap it's sort of like advising someone to do a SFA swap when they have a slow leak in a tire.



As far as autos go isn't there a filter or something in the pan that can get clogged up? Haven't ever opened one up so I'm not sure, perhaps that's part of the problem?

 

i just did the swap my auto trans was giving me 10 to 12 mph and then it started slipping, the next day i went to put it in reverse and went no where, so i pulled the motor and trans and for $400 i was able to get a 5 speed trans and all the parts i needed to install a 5 speed,

 

Dang that's cheaper than I had thought it would be!

 

I would love to swap out for a 5 speed. But I think you got lucky for $400.... Im afraid that would be another day, another time.... and its not so much money as it is time/effort.... conversion is a process....

 

yeah i got the trans for 100 most i have seen are anywhere from 150 to 300. but if u take your time and look around u can find deals. i found someone that sold me the master cly, lines pedals and slave for 20 bucks. got flywheel, clutch new and found drive shaft for 30
