mine is almost ready to go. i still have fluid leakds. after a great deal of trying i have decided that the fittings i bought from blue bird to go in the cooler manifold of the trans will not seal and will always leak so this morning i ordered new fittings from an auto parts store that builds hydraulic hoses. those should be in tomorrow and i will be able to drive mine as soon as i get the hoses hooked up to the transmission cooler. i have a temp probe i am going to hook install in the "to cooler" hose to monitor the temp until i am satisfied that my warning lights are operating properly.

i have the opposite problem with my warning lights. i cannot get either of my lights to work. wrestled with that all day.

We struggled with leaks at the cooling hoses but finally replaced the fittings in the trans itself with 5/8 males which hooked up to our old hoses.

Finally got the check trans light to go out. The problem was the TPS. At no throttle the voltage back to the TCM needs to be at least .54 vdc. Anything less will light the check tran light. We then reset the error codes and no more errors.

As for no lights make sure they are in the right pins in J1. Ted had sent them to me one pin off.

Hi Gary, I think my new fittings have cured my leaks and i finally found out the the LEDs that i was trying to use as trouble lights were defective. they would only light about 10% of the time when i hooked them directly to a known good ground and 12 volts. picked up a couple of indicator lights at an auto parts store that work. not as sexy as the little teeny ones but with me function trumps form. Now the red one self-tests and goes off and comes back on a few seconds later and stays on. the orange one (range limiting) still doesn't self-test so i suspect that it is not in the right place. do you have a drawing of the pinouts for J1? if so, i would appreciate if you could email it to me.

I have tried to drive out of the neighborhood a couple of times and from a cold start it seems to shift fine but after about a mile it begins to limp around with 3rd gear only. I have a temp gauge installed and it has not gone above 200. ted is going to loan me his diagnostic tool to find out what codes are being thrown and help me get out of the limp mode.

A common mistake that many people make is that ALL LED configurations will require a resistor in series with them.

If they are indicator lamp replacements, typically these are units with LEDS that will go right in a socket ment for a lamp, then the resistor is probably added inside by the manufacturer, if it is just a 2 leaded LED the a resistor to limit the current MUST be added.

For most applications using 1 LED, a 1000 ohm 1/4 watt resistor will work for 12-14VDC use, if you need a bit more light, you could use a 560 ohm 1/2 watt resistor.

yes these LEDs supposedly had the integral 560 ohm resisters but they were made in China so who knows.

I know this is real old but I'm getting ready to do an Allison 2000 swap on my 84 Regency. Any more advice from the people that have made the swap?
