Check your mounts,, better a hard shift then a soft shift ,, might be shifting late and not shifting at the proper times .. try driving a 3,,, and see if the shift gets soft.. sounds like a late shift or mount

I have a 99 Acura TL and it is shifting erratically, slipping and not going into certain gears.. . When I put it in reverse it wont engage or when it does it feels like the transmission is about to fall...


The transmission has to come out & be rebuilt

Once they slip your done

Then install all new motor & transaxle mounts
& change your trans fluid every 3 years, on all your
vehicles or they will suffer the same fate as well

Change your power steering fluid every 3 years or the rack will fail like transmissions do

I had the Transmission fluid changed 6,000 miles ago. On occasion it shifts / slips "hard" between gears. I'm now told to have the complete system flushed including a new filter. Please advise if...


Check the vacuum lines going from trans to the intake. Sometimes that will cause it to rev real hi and shift real hard. Even a small leak. They prob jast dropped the pan and changed filter b4. That leaves the oil in the lines there. you have to pump it all out to change it all. My trans in my lincoln just went out. So i would say it wouldnt hurt to change it. Put some lucus trans treatment in it to. Couldnt hurt.

1997 Chevy P-32 step van (panel van, delivery van) with 4L80-E transmission: Truck drives and shifts properly in gears one through three, but slips as soon as it shifts into fourth. It will not pull at all...


the fourth clutch is burnt probably due to a bad 4th clutch piston seal... if you can get a good trans that cheap then you should just put one in it unless you are familiar with internal trans repairs...

99 tercel auto trans seems to slip?


sounds like a vacuum issue possibly look over all your vacuum lines for dry-rot as well as any broken ones this will cause such an issue as well as many other areas to check could also be a stuck sensor

99 Chevy Venture Slams when shifting


If the van shifts ok when cold but hard when hot then the pressure control valve in the trans is bad. When the fluid temp climbs past a certain point the PCS sensor shorts out and stops controlling fluid pressure. This usually causes a whine from the trans (pump) and hard shifting. This is because the PCS can no longer control the pump pressure so the pump now runs at full pressure and shifts as if you were using full thottle all the time - the opposite of what your doing, which is to feather the throttle trying to ease the shift. So now the trans calls for a full pressure shift when your using part throttle and it slams. The (PCS) part is cheap enough but the trans has to be removed to replace it and that's not cheap.

Give this a shot, it often works and it's cheap enough to try.

First, have a good mech carefully check the rediator trans cooler section to be sure there's no leakage of coolant from the enging to the trans coller section of the radiato. This is important!, if antifreeze is leaking into the trans fluid via the cooler it'll cause problems that are otherwise impossible to diagnose and eventually complete trans/torque converter failure.

If there's no radiator problem then power flush the trans and change the filter, then install an aftermarket trans cooler in series with the built in cooler (the instructions with the cooler detail this). It's about $60 for the cooler and maybe one hour to install it.

This whole process will drop the trans fluid temperature 40-50 degrees and often that's enough to get back into a temperature range that will allow the PCS to work reliably again.

If it doesn't work your not out much, if it does work you'll probably get another couple of years out of it.
