Problems with auto tranny

Not withmy wrx .. but we have a family minivan

so here is the problem

i just recently got a tranny oil change for it and it seems that the car slips .. and pulls slips and pulls

kinda like bucking.. but its hard to notice.. but its deff there

the gears engage fine.. and shift smooth


here is an example of RPM from a drive


and were trying to maintain 2500


2500 2800 2500 2600 2500 2900 2500

so normal, slip, catch, slip catch











any ideas guys?

 

What year/kind of mini-van?

Also was it slipping before the fluid change?

 

if it wasn't slipping before then not enough/wrong fluid = overheat?

if it was slipping before, then you prob need a rebuild.

 

no slipping before change and the car has 170k on it

 

Bumpers

 

Looks like someone put the wrong fluid in or didnt put enough in.

I've seen those issues all too often.

 

that what i get for going to jiffy lube =*(

going to the dealership on friday i guess...

 

there's the problem.

I deal with quick lube place's comebacks usually once a day.

All of the issues are usually expensive....usually costs an engine and/or transmission.

Make sure the dealership you take it to documents ALL of their findings.

Most likely jiffy lube will be buying you a new transmission.

 

Thanks, if they do find out its jiffys problem.. do i just go there and talk to the manager?

 

damn, ive been reading up on jiffys problem.. looks like if its their issue.. im going to have a fight on my hands

 

you call the general manager of the store. Start at the top.
