Hello fellow Dodge people.
I hope this is in the correct section.
Recently, I bought a 99 V10 2500 4WD with a 47RE transmission.
It runs great. However, it almost immediately started having shifting issues. Not going into drive or reverse from an idle but, if you rev it a bit, it sort of slams in and, as long as you keep the RPMs up, it works okay. I've researched as much as I could online but haven't found the cause of my exact problem yet. I've experimented and found that, so I don't hurt the trans when it slams, if I rev a little in neutral then let it settle, but just before it gets to idle, I'll drop it in drive and it works fine. Same thing works for reverse. Sometimes I have to do a 'drop into neutral/rev it/back to drive' to get it to shift from 2nd to 3rd, depending on throttle position, load, and speed.
I understand that these trannys have low pressure problems. If I buy a Sonnax? Zip Kit or similar product, would it be a waste of money? I've also read about putting a GM part in it, a servo or solenoid or something like that.
These 47REs are quite expensive to replace and I'm just retired and on Social Security only. I'm able to do repairs that involve the valve body etc.
I've built lots of engines (usually big block Dodges & a few small block Chevys). I used to drag race. I've rebuilt 100s of carburetors, all back in the days of non-electronics, and even tweaked a few automatics, but I don't know if I could rebuild that transmission myself.
I'll try anything that might work as long as it isn't out of my limited budget. I do have some money saved but not the 4-5000 these things cost.
Any and all advice would be appreciated muchly.
Thanks.
