For older computers: Older computers that came with at least Vista, are sometimes limited on how much RAM can be installed even if your running a 64bit system (for example, this PC that I am on... Is from 2007 and came with Vista, I have maxed out the RAM to 4GB which is the limit of the motherboard) so what do I do if I want it to go faster? The best upgrade for an older PC is installing an SSD. In most cases, a mechanical Hard Drive is the bottleneck in old or new systems. For New Computers: You should have at least 8GB RAM (16GB RAM is the norm), An SSD for the system drive, and mechanical drive(s) as data storage.
Was the D104 diode clipped or removed? If not, remove the whole diode... If this is not removed, you won't get full modulation or watts. It must also be peaked to match the new driver and final. This is just off the top of my head without you providing final and driver information, also assuming you upgraded the CB.
Check to see if any of the wires going to the solenoid are missing insulation. In most cars, the wires going to the starter are always grouped really tight and very close to the engine block. It doesn't take much movement for a slightly bare wire to short things out in this situation.
Either the fluid is very low, or fluid is not being pumped through the transmission. Start out first by checking the transmission fluid while the truck is at operating temperature. If the transmission oil is low, check under the truck for any signs of leaks. If it's leaking from the transmission pan, transmission lines, or at the radiator... it's usually an easy fix. If your transmission fluid is ok or low without signs of leaks, have it towed to a transmission shop. Don't drive it or you may risk more damage.
