Help no reverse?

for some reason i cannot get my charger into reverse. at first i thought because my shift linkage was screwed up from my headers that was the cause. but i bought i cable shifter and it still doesnt want to go in reverse. i put it in reverse and it goes forward. any suggestions?

the cable tube may have melted thanks to the headers and the cable may be fraying, have you inspected the whole cable? or is it brand new?

If everything is adjusted correctly, there's your problem. The A904 just does not hold up to a lot of heat and abuse. HAve you checked the fluid to see if it looks or smelled burnt?

First thing to do is remove the cable end from the transmission shift lever and compare the position of the trans lever to the shifter position. Have an assistant sit in the car and put the shifter in Reverse, compare the position of the cable end to the lever that you have manually placed in Reverse (second detent from the rear).

If the transmission lever is actually in the correct Reverse position and the trans still misbehaves, the problem is internal.

A well built 904 will take a tremendous amount of abuse.

It would need to be a small block 727. You would need a shorter driveshaft.

The two internal components used for Reverse are the front clutch and the rear band.

The front clutch is also used in 3rd gear but a dirt track car might never use 3rd depending on gearing/track length, etc. If 3rd gear is OK and there is no Reverse the problem is in the rear band/servo.

The condition of the rear band/servo can be visually checked by simply removing the pan; the front clutch circuit can be tested with compressed air but the clutch itself can only be inspected upon removal.

DW, my friend, the statement "there's your problem" (referring to the 904) is just the kind of thing that starts thread wars. It is judgemental and has no proof. It may very well be true and a well documented fact, but to just toss it out there like that makes it sound like an opinion.

The whole sentence, "If everything is adjusted correctly, there's your problem." infers that correct adjustment does not work, so then incorrect adjustment is required.

I know how easy it is to let our thoughts get ahead of the keyboard and that it probably came out differently than you meant.

Just my thoughts, no offense intended.

Well that may be true in some applications and I am very limited in my auto tranny knowledge other than I remember that the old 727 was a good unit. I don't travel in the same "circles" that you do (pun intended) so I can't say that I have heard that before.

However, 904s were built, and many did perform well in stock applications.

Now, how did you know that his tranny was abused? He didn't say anything about running it hard, did he?
