4R70W not shifting into 3rd or OD
Okay, save me some trouble of searching.
1994 4r70w, upgrade to 2000+ valve body, j-modded with 2800 stall converter. Took it for a spin last week, entered the ramp to the interstate and let her rip through 1st and 2nd., about that time I had to let off the throttle and let it ease into 3rd, reapplied the throttle to just cruise and no 3rd, revving like it was in neutral. Luckily I was able to coast to the 1st exit which is my exit, when I slowed down to turn off of the off ramp I was going slow enough for it to kick down into 2nd so I limped back to my house. I let it sit until today so I pulled it out of the garage and let it warm up to check the tranny fluid level and was a little low. Topped it off and took it for a spin around the neighborhood and no 3rd or OD, meaning gear selector in drive and tranny still in 2nd, not free revving like it did on the interstate. Any ideas on what possibly be the issue? I'm hoping it's a simple and inexpensive one but I'm not banking on it.
