Unless you are an expert at rebuilding transmissions this is a job you might want to leave to a professional. Once you start to take apart a tranny the odd are when you are done you will have a lot of parts that you dont remember where they went.

Why wont my 2004 chevy impala go in drive and only go in reverse ? Will i need to replace my ttransmission again after only 1 year ?


If you bought a used one, Probably. Many things inside the transmission can do this. But the most common is the band breaks for the forward drum.

My 2001 tahoe won't go forward only in reverse. What can cause that?


Broken band, bad seals, burnt clutches. My guess is the band. No shop will just replace that though. A rebuild for that transmission will run around $2000.

I have a 1995 ford aerostar that park doesn't work. It says im in park on the cluster but the vehical will still roll if i dint block the tires.


Inside your transmission is a Park Band. It works like a break to hold your vehical from rolling. Most of the time this will break if you park on alot of hill and when it rolls either forward or backwards. You will have to take it to the shop to be repaired or if you know how to replace it your self. The transmission will have to come out in order to replace the band.

My 97 tahoe will not go into reverse but good in all forward gears


Inside this type of transmission reverse is applied with a special clutch band, that band is usually the first thing to wear out in any automatic transmission, no reverse is a very common failure and I see it often on FixYa, the only solution is to overhaul the transmission, since replacing the reverse band requires the transmission be completely disassembled.

1997 chevy blazer awd - no reverse and slipping in forward - oil good no leaks - whats this?


It sounds like the sun shell inside the transmission that is faulty, and that is due to a manufacturing process..
Unfortunately, this problem requires a rebuild or replacement of the transmission. The same thing happened to me about a month ago with my 97 Blazer. It cost me $1200.00 for a local transmission shop to rebuild mine.
"
The "sun shell" connects the reverse input drum to the sun gear. The 2/4 band wraps around the reverse drum. When the reverse clutches are applied the sun shell spins the sun gear. When the 2/4 band is applied the sun shell holds the sun gear from spinning. This is why when it breaks you lose reverse, second and fourth"

The reverse gears are not working.if you put the reverse gears it will accelerate infront instead.what do i do?


It sounds like the reverse band broke. Typically with automatic transmission when you put the transmission in reverse a couple things happen. Usually, the forward clutch engages and the reverse band engages holding the reverse drum from turning, which causes the planetery gears to make the vehicle move backwards. If the band breaks there is nothing told hold that drum from turning and you have a forward gear. The bad news is the trany is going to have to come out to be repaired and usually the reverse drum is one of the first things to go into the trany, so it has to be completely disassembled. Take it to a transmission shop have them check it, hopefully it's something simpler.

2004 pontiac sunfire won't drive forward but goes


That would be your transmission. The only way to fix it is to have it rebuilt or buy new, both are around the same price sometimes. Sorry to hear your troubles.

Reverse does not work all forward gears work fine however it does shift a little harder since reverse went out


Man, I have had that problem before in a camaro years ago and it was that the reverse clutches went out but, you could drive it forward and had to repair tranny.

The 5r55w transmisson is known for wearing out the case where the front and middle band servo pins go thru. If it wore the front band servo, it would slip in 2nd. But if it slips in 1st and 2nd it sounds like it could be a weak forward clutch. How many miles does it have on it. If you can get it up into the higher gears, does it slip in 5th. 2nd and 5th use the same band to apply them. Are you gettting and overdrive off light flashing? IF yes, what codes?
