Car won’t drive in any gear but reverse Mechanic's Assistant: How old is the transmission? Have you checked the brake switch? Transmission is approximately 200000 miles old Where is the break switch Mechanic's Assistant: What is the make/model/year of your transmissions? 07 impala 3.5 Mechanic's Assistant: Are you fixing your Impala yourself? What have you tried so far? All I looked at was the switch cable to make sure it was still connected properly at first it was driving in 1 and 2 but now it’s only driving in reverse I had to drive in reverse to get home Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I think that’s about it unless there is anything you want me to check

Jay, I'm sorry to hear about your transmission issue. Do you have any warning lights on in the dash?

Check [engine](/topics-engine-chevy/) and tire pressure but thats because I'm missing a sensorThe check engine is because of my crank shaft gear
Automotive Expert
Ok, did you check the fluid level on the transmission?

Fluid is a little bit above the wanted level
Automotive Expert
OK, prior to loosing forward, what happened? Did you service anything? Did you hear any abnormal noises?

Not at all. I was in drive and everything was good then I came to a complete stop and I hit the gas and it was like it was in neutralI switched it to park then drive and still the same thingBut it was driving in 1 and 2
Automotive Expert
MAnual 1 and 2 would still allow the car to move?

If I was driving then switched it to drive it would drive in that gear then until I came to a stop

But then it stopped working and only reverse was working
Automotive Expert
OK, so I have some bad news. IT sounds like the 2-1 band, possibly more have been damaged or worn out in the transmission. You will need either a rebuild on your unit or a replacement unit. I am attaching a document that outlines all the possibilities for no drive.

only options are to rebuild the transmission or get a new one?
Automotive Expert
I guess you can get a used one, but then you run the risk of getting one with problems. There may be the option to repair just what is bad in your's, but if you are going to the expense to remove the transmission, it will be little more to finish rebuilding it and replacing all the seals, clutches and such.

what would be the best option you would recommend if I don't have much to spend but I need a fully functional vehicle?
Automotive Expert
That depends on how long you are keeping it AND if you have a quality transmission shop around. IF you do, talk to them. If not, get a GM rebuilt unit. The GM units come with a 3 year, 100000 mile warranty. Shops that rebuild them may be a. year and 20000 miles.

Do you know around how much that will be?All together?As far as the transmission shop what are the chances of me fixing it myself?
Automotive Expert
I have not priced out one in a long time, but a rebuild at a transmission shop may be around 1500, a rebuilt unit from GM, 2500, but that is a guess. That last one is a loaded question. Maybe I should say it this way, there are career technicians that won't touch transmissions. Myself it depends on the transmission. So I have troubles recommending that the average user at home work on the transmission.

If it's just the 2-1 belt all I have to do is just replace that right?Well take apart the transmission and replace it and put everything back right?
Automotive Expert
I wish it was that simple. Getting the transmission out itself is a pain. the engine needs to be supported then the subframe removed, the transmission or drop the engine/transmission as a unit and split it from there. I cannot say for sure if the 2-1 band is the only issue, it would take dismantling the transmission and inspecting it. Please understand, I am not trying to talk you out of it, nor am I suggesting you can't. I simply want you to be fully aware of what you would be getting into should you take that route.

I understand. You are just trying to give me the best optionsI'm just trying to get a clear understanding of everytime because I need my car but I don't have that amount it takes to take it to a shop

Automotive Expert
Absolutely. Perhaps consider this, taking it out is the bigger expense, perhaps you can remove it and get it rebuilt.

Can you go into detail about this?ok
Automotive Expert
That is an itemized list of what could possibly be wrong. IF I was taking it apart, I would check each of those things.

All of those items are in the transmission?
Automotive Expert
The linkage is not, but I doubt that is the issue based on what you have told me.

Do you have a personal number or email I can contact you from if I have any more questions?also since it goes in reverse and it was going into manual gears can it be the forward clutch?
Automotive Expert
IT could be the forward clutch as well. You can reply to this thread to follow up with me. I don't give out my personal number, sorry.

Ok. How long will this tread be available
Automotive Expert
Indefinitely.

Ok. Great. So your like my personal mechanic angel on my shoulder lol
Automotive Expert
For this issue, yes.

Do impalas have forward clutches? If so do you know where it is located?
Automotive Expert
It would actually be the input clutch. I think these will help you.

I can eliminate my solenoids because my car goes into reverse correct?
Automotive Expert
Correct and it would still move in one gear at one speed if it did have a bad solenoid.

What's the chances of it being a solenoiddo you think it would be a good idea to replace all the bands, clutch pads, and clutch plates?
Automotive Expert
Odds of a solenoid are none. I would replace all seals, clutch plates, possible steels, and seals.

Ok. Could it be the crank shaft or cam shaft gear?
Automotive Expert
No, That should not prevent it from moving.

Hey I have a questionDo you know the placement of all the check balls in the transmission?
Automotive Expert
The 7 check balls go in the valve body side as illustrated in the diagram. I use just a slight dab of petroleum jelly to hold them.

Is that for the 4l65e?the balls are different sizes. Which one goes where
Automotive Expert
Sorry I clicked the 4L65E, one moment, I get the proper one.

Also how many check balls are there total for the 4l65 e
Automotive Expert
This document will answer all of that.

4t65e\*
Automotive Expert
YEs, that latest is for the 4T65E.

I have 11 balls in hereHow many is it suppose to be?It's a extra big oneI have a extra ball. It’s a big oneI have all 10 in the holes and I have a big one

I have a ball next to that one that was already in that hole. Is it suppose to be 2 there?

This a better one
Automotive Expert
I think its in here, internal to the valve body, 324.

I think that’s the wrong thingI’m asking about an extra ball. That’s other pieces
