tranny on my parts truck reads t19-148

is this the wide box with granny low?

if so guess what...i got a slush box for sale:D

I think so...
Ratios should be:
6.32 1st
3.09 2nd
1.68 3rd
1.00 4th
6.96 R

Be careful - the top covers (usually where the numbers you found are located) can be swapped amongst most of the t-19 on the market.... So you should check to make sure it really is a wdie ratio - spin the input in 1st and count the number of times it takes you to go around to get the output to go around once....

I have 2 T19s- one is wide(6.32:1 1st), one is close(4:1 1st) The numbers on the top cover read T19-148. So. . . if the tranny is in the truck still, you could pull the top cover and count the # of teeth on the input shaft. Should be 17 for wide, 13 for close.

Look for the tag attached to one of the cover bolts. It will have a code which indicates the ratios. If memory serves me it's C41-19 for a wide and C41-21 for a narrow, you can check this on the BB.

The T-19-148 means nothing...
