Hoping for a little insight on how screwed I am on my current project. Bought a 1984 K5 blazer with a beat 305 and 700r4 trans. I found a mildy built 350 to swap it out. I ended up getting a B&M Torque converter to help adjust to the bit more of hp. After trying to put the truck into gear noticed it would not no matter what I did. I did not notice any weird clunks or anything at all. I’ve never replaced a torque converter before but the information I got said that this one would work for my setup to later finding out I put a 30 spline converter on my 27 spline input shaft after checking my old stock converter. I just verified I still have pump pressure on trans after shooting fluid half way across my garage. How much damage should I expect on the input shaft of the transmission? Should I expect to have to replace the transmission? Bumming because I’ve been pushing to get this truck done. Appreciate any insight since I’m a newbie to these and still learning.
Are the pictures after you took it apart? If so, do you see any damage? I don't...but it's not a very clear picture, taken too far away to see much.
Sorry yeah the picture of the shaft is before I put the new converter on. The weird thing was I heard the three clicks that I thought you’re supposed to hear while installing them so I thought everything was OK
Yup, you have to also know about the 30 spline upgrade they did in the mid 80s, and what year transmission you have. Take it apart and inspect things. I don't know if the 27 spline shaft is a free fit in the 30 spline converter, or not. Been a long time since I played with a 700r4.
