tcm fuse keeps blowing
My 94 has a e40d trans. I stopped for a stop sign and went to go and felt like it was being held back. The od light was on. On the shifter. So I shifted it to reverse and went fine. Put it back in drive and still was bad. I shifted it to low and works good .and if after going will work fiine but no od. Looked under hood at maxi fuses and one was blown. It is the tcm # 22 on my truck. So I replaced it and it blew again. Wires seem to look ok nothing that jumps out at me as wrong. Anyone have any info or similar problem ? Thanks.

Ok...so I put a vss in the rear end and still... it keeps on blowing the fuse. I have a power probe . And read voltage on one side of the fuse under the hood...and continuity on the othe side. Doesnt that mean there is a direct ground on that side? But I cannot find it.... pulling my hair out.
