Just finished rebuilding a T-350 and having problems with the 1-2 shift. For reference, I rebuilt the trans doing the "double feed direct modification", blocked the 1-2 accumulator in the case in the full forward position, tig welded up the 2-3 accumulator hole on the separator plate then ground it flush, I also drilled out both the 1-2, and 2-3 feed hole on the separator plate to .125".
I used Alto red eagle frictions in the direct drum, and Borg Warner clutches for the rest. I replaced the band, filter, and all O-rings, and sealing rings.
We installed the trans and it seems to work okay in that it has all 3 gears, and reverse. The problem is that it only stays in 1st gear for about 5 feet before it shifts to second. Even if I put the shifter in L1 to manually lock it in 1st, it still won't start off in 1st, or won't stay in first. As soon as you let off the brake and begin accelerating, it immediately shifts to 2nd. 2nd & 3rd seem to be very strong. Any ideas as to what I should be looking at?
If it matters, when I had the trans out, I managed to bend the S link up pretty bad. I *think* I put it back in correctly though as I lined up the manual valve so that it was just flush with the end of the VB when in the "D" range.
At this point, I'm going to guess that it is the governor sticking, but I thought I would throw it out to you guys to see your thoughts. I can build the H*E*DOUBLE HOCKEY STICKS out of 700's and 4L60E's but I've just not had any experience with the T-350's. Thanks in advance to anyone who replies!! :welcome: :welcome:
