Reverse went out on 1978 Chevy pickup

I have a 1978 Chevy pickup w/a 3 speed automatic transmission. The reverse gear suddenly stopped working. It will idle in reverse, but will not move even when I rev the motor. I dropped the pan and cleaned the screen. All other gears work fine. What else can I do to fix the problem? (Besides take it to to a shop)

Nothing. Also it will be much cheaper to find a used matching transmission with low (less than 80k miles) than having a shop rebuild the old one. In most cases the used transmission will far outlast the rebuilt one. Check on the web by Googling "used transmissions".

Remove the valve body and clean it. Otherwise remove the trans and rebuild it. Reverse is the first in the case and last out. 350 lock-up I'am guessing.

    Dave has a good point. The only problem is that I owned a trans repair shop and wouldn't recommend a used trans. I don't see the logic to used vs. completely rebuilt,if done correctly. A 350 has been around since the 1970's and is reasonable to redue or just pull and fix.

1991 chevy pickup automatic no reverse why there is no reverse gear

Occasionally a person can have good results by checking for low transmission fluid levels or by changing the tranny fluid and filter. However, I am sorry to say, losing reverse gear USUALLY means it is time to get a new transmission. If you are on a tight budget, you can always dedicate a day or two to removing it, and put in a used one from a wrecking yard.

My 2001 eclipse automatic would not move in reverse,drive and all other gears just for a momment but now works but has no power from the stop position and takes forever to get up to speed

The slip disks in your automatic transmission and some synchronizers are worn out. Your transmission needs to be overhauled and repaired.

I have a 1978, 2wd, old chevy pickup with a 305 engine in it. It has a automatic transmission. It recently has not been wanting to shift into reverse. Any help?

I'm assuming that you checked the fluid and it's full. If the fluid was low and you had to top it up, did you run the tranny through the gears, stopping at each gear for a couple seconds? Do this a couple times, down and up. When was the last time you changed the fluid and filter, every 80-100,000 miles.
Check that the vacuum is good to the modulator valve, round thing at top rear on passenger side of transmission. Remove it and tip it down, if any oil comes out replace it.
You could try adding some Lucas Trans Treatment. If this helps, you are looking for a rebuild or another transmission in the reasonably near future. Read the instructions on the back of the bottle.

Have all gears that work find but will not go in reverse it a 5 speed

Is this a new truck to you? Some manual's have a manual reverse lock-out, meaning you have to engage the lock-out to shift into reverse. This is usually done by pulling up on a small lever just under the shift knob.

Otherwise, the lock-out is inside the transmission and if that breaks, the transmission has to be removed to fix it.

The other possibility is that you don't have a synchronized reverse gear. It will not automatically sync with the engine speed. Try lightly putting it in reverse while letting the clutch up to the engage point, you know, right where the clutch first starts to grab.

Whining noise when engaging 1st or reverse.

i had a nissan pickup that would whine in all gears except started out with 1st then reverse then went to the rest...solution was new transmission...or rebuild cause the syncronizers or the gears them selves are being chewed up...the new transmission was cheaper then a rebuild. or take it to somewhere that will do free diag on the transmission.

Suddenly automatic transmission would not go into reverse

seems like your gear linkage is either broken or come off, if the linkage is ok then u are looking at a replacement gearbox
