92 a4ld grinds into 1st gear

[kraylake]

when i put my 92 into D, it grinds into gear, then takes hold, then drives fine in all gears, whats my problem?

 

[shaggymane]

Do you just hear the grinding or can you also feel it through the gearshift?

If you can feel it through the gearshift that makes me think it might have something to do with the parking pall not releasing all the way or slowly.
That would be unusual.

See what the other guys say

update...was sitting at a traffic light in OD, light turns green car wouldnt move. i dropped it down into 2 and it moved, mannually shifted into OD once car was moving and it shifts perfectly. stop at a light, car wont move, drop it into 2 and car moves.

whats going on?

Did you check the fluid level in the transmission? Your shift cable might be sligntly out of alignment or the Z link could be bent.

 

[kraylake]

fluid is fine, filter recently changed, the shifter does have some "play" in it. i also shud say that i had a delayed shfit into reverse condition, i replaced the reverse servo orings, that did nt help, so i installed the reverse servo extender pin, that fixed reverse but thats when first gear began to mess up.

i also replaced the vacumn modulator cause it wasnt shifting into OD...i now shifts into OD perfectly.

Did you grind down the tip of the extendo pin? It will cause the band to drag if it's too long. Maybe this is what is causing the grinding noise in 1st gear?

 

[kraylake]

i did not...and the sound was like grinding metal.

 

[BrooklynBay]

What was the reason that the extendo pin was installed? Was the tip of the low/reverse servo chipped?

 

[kraylake]

the tip of the servo was fine. i had read that IF the oring replacement on the reverse servo didnt fix the no-shift-into-reverse condition that you shud put the extender pin it. Which i did. There were instructions to grind the pin down but it didnt say how much to grind so i didnt grind it at all.

 

[BrooklynBay]

The servo comes in three different lengths. Two out of the three were discontinued. Take out the extendo pin before it does internal damage to the low/reverse band.

ok, in attempting to remove the extender pin, i broke the tip of the servo shaft off. I had a spare servo so i installed it. The fluid in the trans was dark, smelly and had some metal flakes in it. (mind u i probably only dove the car with the extender pin installed 10 miles) When test driving, there was no change in trans function. It goes into reverse on a small delay, you can feel it go into Drive but the car wont move when u accelarate, shift into 2 and the car goes, after u get to about 2000 rpm u can manually shift into OD and the car goes through its shift sequence just fine. Come to a complete stop in OD and then accelarate, the car wont move. Put it into 2 and it will go.

Oh and the z link was fine, but the hole that the z link fits into in the valve is a bit oblong and presented some sloppy function, dont know if its enough slop to matter.

What shud i do now?

Install the TransTec Viton D ring kit on the low/reverse servo to help with the delay going into reverse. A manual valve index sleeve should help with the rounded hole in the manual valve. You should get these parts:

It's a good idea to rebuild the valve body, adjust the bands & kickdown cable, and install new valve body gaskets. How is the reverse bore? You might need this kit if it's damaged: http://www.transmissionpartsusa.com/C3_A4LD_4R44E_Reverse_Servo_Sleeve_Kit_p/400-05653201k.htm

 

[kraylake]

do i need to remove the valve body to install all this?

 

[BrooklynBay]

You don't have to remove the valve body to install the manual index sleeve or the Viton D ring kit, but all of the other parts require removing the valve body.

 

[kraylake]

ok got all that stuff above installed, adjusted the bands, adjusted the kickdown cable. It shifts into reverse nicely. when i put it in OD or D, it wont move, if i put it in 2 itll move, if i put into 1 it wont move.

so, i can put into 2 and go, then manually shift to D or OD and itll shift fine, goes thru all the gears, upshifts and downshifts fine. But once i stop and if im in OD it wont move out again untill i shift into 2 then itll go.

 

[BrooklynBay]

Did you adjust the shift cable?

 

[kraylake]

no. is that in your list of useful threads?

 

[BrooklynBay]

Yes it is. Check # 19.

 

[kraylake]

two things, first, i adjusted the shift cable per instructions and it didnt fix my problem. second, if i go out and buy a replacement transmission will an A4LD from any vehicle work?

 

[BrooklynBay]

There are different variations of the A4LD (3.0L 4.0L, 2WD, 4WD, etc). Try to get one as close to your model as possible.
