1984 Chevy C10 350 700R4 computer gone, running external electronic lockup for overdrive
Last night after coming to a stop upon starting I only have 1st gear; it would not shift into 2 / 3 / or 4 OD. Limped to a parking lot. Checked the trans fluid and trans temp; both normal. Trans fluid like new, not burnt, smelled and felt like new. Shut engine off, crawled under and visual inspection all looked normal; no leaks, linkage intact, all wires looked okay. About a 15 minute inspection. Started up engine to limp along in 1st gear.
Truck started off okay and now shifted okay… I have started it again and went on short 1 ~ 20 miles drives. No apparent problem. Seems to be shifting okay. Now I am scared to death of getting stranded on the highway or towing my 2000lb boat/trailer.
My guess is this situation is not an isolated incident. Any ideas or suggested next steps?
Thanks in advance.
