Yes. Could just be that the linkage is not engaging reverse properly, try disconnecting the linkage at the transmission and manually putting it in reverse, if this works then you just need to adjust the linkage appropriately.
Time for a transmission rebuild.
NO. It will not even Begin to work
NO. Not even close.
Weight of the vehicle
A Chevy 305 is not a transmission it is a motor. If you mean a Chevy turbo 350 then the answer would be 3 different forward speeds and reverse.
yes, but it wont handle the torque very long.
My trailblazer works fine both forward and backwards! Yours however sounds like you blew the reverse band in the transmission and need a new tranny. Or your against something that is holding you from behind.
reverse drum inside of trans is stripped out the fix is teardown unit and replace with abeast drum from transtar
The input sunshell splines have stripped or the hub has broken off. This will give you 1st + 3rd gears only with no reverse, 2nd, or 4th gear.
the transmission is smoked needs to be taken out and inspecked or there is a LINKAGE PROBLEM GOOD LUCK JOEY
Could be a pump problem or broken planetary. Regardless, the transmission will need to be disassembled.
