Ok Guys & Gals I Need Some Help I've Got A 1994 Chevy S10 Blazer 2 door with push button 4wd & a 4.3 liter Vortec Engine and it has no reverse all forward gears still function properly but i have no reverse and no neutral from neutral gear on down to 1st gear it goes forward and when u put it in reverse u can tell its in gear but it just freezes up & wont move at all under power but if u shut it off itll move forward and backwards in all gears ive redone linkage on tranny and i know 4 a FACT!!!! That the linkage is good 2 go so any help is very much appreciated

 

You need a trans rebuild. The failure you have described is very common.

 

U can tell the gears are there whenever u put it in reverse it just doesn't move

 

Google "4l60e sunshell failure" and you will learn all about what I am referring to.

 

If it is binding in rev you have damaged rear planetary gears. Stripped shell will not bind in rev. It will have 1st and 3rd gears forward.
