Okay, I got the CV axles out and the shift link along with the manpower connector, but what is the lift points of the 5.3 ls4 motor? Need to figure out where to put the engine support bar chains to. Also 0 psi from the transmission in park, neutral, and first.

I would use the rear of one of the heads for one spot and the front of the engine for the other. Attach opposite so it holds it straight so it does not roll over.

That sounds fun to get to, lol. Thanks I will give that a shot tomorrow. So use head bolt from both side of the engine? Should I get higher grade bolts that will thread into the head?

When I warm the car up after a hour it would drive fine then all of a sudden it wouldn’t go in drive or reverse. The RPMs go up when I push on the gas but won’t move.

Okay, so I'm just about to the point to pull the transmission weathers been crappy so it's taken me longer than it should but I got everything disconnect and off except the bolts that hold the transmission case to the engine by chance do you have a diagram or anything showing where all the bolts are that connect the transmission to the engine? I saw someone with a 3.5 take the transmission out and it looked like two bolts where hidden. I see what looks like four bolts by the differential are there any more other than around the flex plate?

This sounds like you are low on transmission fluid or the pressure control solenoid is out. here are instructions on how to check the fluid level and we should run the codes as well:

AUTOMATIC TRANSMISSION 4T65-E

Bottom Pan Removal .................... 7.0 liters (7.4 qts)

Complete Overhaul .................... 9.5 Liters (10.0 qts)

Dry .................... 12.7 Liters (13.4 qts)

Measurements are approximate

Can I ask if the gear selector light are working? Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

I could be wrong, but it looked like there were four bolts around the differential that connected to the engine? Also thanks for the picture.

What do these bolts do? Do I have to remove them? Looks like a baracket coming from the transmission and bolts onto what appears to be the engine?

Yes, that is a support bracket. Remove the 2 bolts on the transmission and the 2 bolts on the block.

This sounds like you have a transmission gear position sensor that is out. Here is the location so you can change it out. # 811 on the diagrams below.

Check out the diagrams (Below). Please let us know what happens.

My friends transmission would go in reverse but not in drive. She told me that she just started driving it in second gear for probably fifty miles. Just went on her merry way. Next day it she started the car, tried to put in drive but still did not engage so
went back to second gear and got three blocks and engine shut off. It started but none of the drive gears worked so drove back home in reverse. I have noticed and warned her that she backs into her driveway and often sticks it in reverse before car comes to stop. In case that helps anyone. I did not know until after all these facts as she remembers.

She did say her brother put in a quart of trans fluid to see if it would go into any forward gears. No luck.

I checked the transmission oil with dipstick and it was still pinkish but darker, with no real burn smell that I could tell. I had read on line that a fluid supply line is known to crack and cause only reverse to work on this car. So I dropped the transmission oil pan and found what is on this picture at the bottom of oil pan. This has to be important? Can anybody help? Thanks

Welcome to 2CarPros.

Sorry to hear about the poor Impala,
That is a rather important part, namely it is the actuator tab from the direct band. That band is what locks the forward drive hub so it moves the car forward. That is part 68 in the first picture. The best repair is a rebuild of that trans or replacing it with another one. Nothing can be done with it in the vehicle though. It has to come apart. That part is now floating free in there and it could move and lock up at any time if the car is in motion, that would do a lot more internal damage.

As for the hitting reverse while in motion, that could easily cause this as that would cause the transmission a severe shock loading on that tab. The car moving forward will still have a lot of inertia and putting the car into reverse would put all of that weight onto that tab as it tries to release.

To me it looks like it is time for a rebuild. You have metal throughout the unit you would be gambling to try and fix it with a complete tear down. I can give the rebuild installation and diagrams if you plan to do it yourself. You can get a rebuild kit from rockauto. Com.

I have a question about the pump shaft the original one had this blue hard plastic o ring the new one did not. I tried to remove the o ring and it looked to be damaged. Is it ok to install the shaft with out that plastic part or do I need a pump shaft with it. The new one was exactly identical except the blue plastic part.

Ken if you can give me a link to the rock auto kit I would appreciate it it's the 4t65e-hd but from what I could see on the teardown all the metal was contained in the pump looked like a clean break. Or if you can find a kit that's built better than factor I would appreciate that as I see alot of 06-09 impala ss have problems with the drum failing.

It looks like the only diffrence between the hd and non HD model is the differential. So what rebuild kit would you recommend I dont have paddle shift but can manually pick gears 1-3.

Should I just get the Master Kit (Overhaul Kit + Friction Clutches and Steel Clutch Plates) or is there a different kit that I should purchase? Never mind about the above post I guess that's the seal ring and its meant to have a cut in it. Never looked that close at an input shaft.
