What would cause it to stick in 2nd gear? It is a 92 so I know it is not limp mode. It has manual low but if you take off in 2nd or D it just takes off in 2nd and stays there. Neutral Park and reverse are fine.

i take it is a overdrive in a shadow?? or a van if its stuck in 2 it is in limp thats what they do it so you can drive to saftey you can try changing the 2 speed sensor 1 that is between the 2 trans lines right above the selinoid pack the other is straight across it about 8 " the 1 will moe than likley have a bunch of 'crap' on it there will be you're issue these are mangnets on the ends so they only pick up metal so you can guess whats wrong after that

It is not stuck in limode because it is not computer controlled except the OD. There is also only one speed sensor. It is not a stuck throttle valve because it would shift either too high or too low but not just hang in one gear, especially second. It might be a hung govenor, I guess that could hang it in one gear.

None of the 727 transmissions are computer controlled when it comes to 1/2/3 shifts except when you get into the RE trans with the electronic governor circuit. I used to know what caused this as we would have it happen on the Diesel trans we upgrade, start off in second, but I can't off the top of my head remember what caused it, something to do with pressure , but this was on an RE trans .... carry on

A test gauge on the governor pressure test port will tell you if the governor is the problem, if the governor tests OK the problem is likely a stuck 1-2 shift valve.

As Bill stated, the high pressure at idle is the reason it won't downshift and the low pressure at speed is the reason it won't upshift to 3rd. You need about 10 psi of governor pressure for every 10 mph.

Is there something in the VB that could cause this? There is no differance after all that.
On a side note I did notice the trans is a 94 and there is a recall for snow plows in 94, is there a way to update the spacer plate like the recall plate? Dodge won't sell me a plate and they won't install it because the truck is a 92 ramcharger, not the original one.

I am not new to this, I have rebuilt sucessfully many touque flites 3 and 4 spd, hydraulic and electronic. I am not a parts replacer, I am a profesional mechanic ASE master certified too, how many "parts replacers" do you know that happen to have a trans preasure tester or a very expensive Solus scanner? I also have enought spare parts in my garage to build another 4 of thease things from scratch but I just wanted to fix this one without building another and it has turned into fixing someone elses mess, just once in a while something comes along that just stumps a guy and so I figured a few more heads might be helpfull. Mabey I am just overthinking this and over looking something simple, so I thought I would ask for some ideas. To the rest of you, THANK YOU SO MUCH for the help! I noticed it has a shift kit in it, looks like a TF-2 with the updated preasure spring and stuff, mabey they screwed something up there

If it's not already in a little Nash Rambler, put it into a little Nash Rambler, look for a Cadillac, make sure your horn goes, Beep Beep, Beep Beep, Beep Beep Beep, pull up along side the Cadillac, roll down your window, and ask the driver of the Cadillac, "Hey Buddy how do I get this out of second gear........." Good luck, and have a Happy Holidays.
