i drilled the hole in the seperater plate when i wasnt suposed to when i was installing my transpack. i was going for the stret strip but i misread the directions and drilled the support plate and only installed one 1/4 inch check ball. as of now its installed and i have no reverse can i rip it apart and weld ip the 3/16 hole i drilled to regain my reverse gear? would my reverse come back? the troubleshhoting guid says.......no reverse or third= middle,supportor transferplate not installed properly. im hoping the hole is my problem. thanks -kyle

welding that plate is going to distort it terribly and it had to be perfectly smooth to seal properly. you might wanna bite the bullet and get another kit. where did you put the ball and did you put it in the valve body or above the plate in the transmission.

Don't know that much about auto trannies but there is more than one way to plug a hole. You can go down to napa an expansion plug, like a freeze plug to install. I don't know if the have them in 3/16 I have a 3/8 so they do get pretty small. You could also tap it for a machine thread or pipe thread. You could also get a piece of 3/16 cold rolled round and fuller the end( just tap it with a hammer until the end is a little bigger, cut off the appropriate lenght and tap it into the hole. Then take a punch and tap the other end while backing up the first end. In other words make a rivit out of it. Or just epoxy the piece in there.

walker he cant do what you suggested because the plate sandwiches between the valve body and the transmission case itself. besides if by chance that plug would fall out or work loose goodbye tranny. did the kit come with a new plate or did u reuse the stock plate?

special70gmc · 12-09-2003, 07:33 PM

i came w/a new plate, now that i think about it i put the trans to gether on a bench and probly put the balls on the top side on the trans. would this cause no reverse?

cableguy0 · 12-09-2003, 08:20 PM

they are supposed to be on the transmission side.is this a fresh rebuild or was it a known working unit that you added the kit to? if its a fresh rebuild see if its engaging into low gear. low and reverse share a lot of things inside the transmission. if low gear isnt applying that would suggest a problem in the transmission itself. but if the transmission was working ok and was used before you problem is somewhere in the valve body. whos shift kit was it. was it a tci kit?? or...

special70gmc · 12-09-2003, 08:22 PM

it was working before i did this. this kinda sucks -kyle

it was a b&m kit

cableguy0 · 12-09-2003, 08:41 PM

i would pull at apart and make sure the ball is where its supposed to be. and if it was me i would just get another kit with a fresh plate

jcueckert13 · 12-09-2003, 09:28 PM

in my shop class i helped a friend do the exact same job. like was said earlyer check the position of the checkball. i doubt there is a way to patch the hole.

special70gmc · 12-10-2003, 08:49 AM

but my problem IS in the valvebody area? correct, that will limit my search then at least. thanks -kyle

Between the check ball in the wrong spot and the hole drilled in the wrong spot the fluid is not being routed were it needs to go!Get a new plate,as someone else said it needs to be flat.I dont know if you could weld and grind it flat without warping it.Double check every thing as you put it back together.The balls must be in the right place and the right #of balls.Make sure the oil transfer slot is in correct.

special70gmc · 12-11-2003, 07:29 PM

ok i didnt get into it yet but i did put the rear on stands and put it in reverse it spins imidiately and accelerates whe i hit the gas but just doesnt work under a load. any way im still gonna open it up on saterday i think and see whats wrong. thanks -kyle
