Hi,

Need some input from the wizards here please. Here's the story using the guidelines from "Common Sense":

1. 1996 Ford Explorer
2. 4 wheel drive,
3. V6
4. 108K miles
5. rebuilt transmission from Roadmaster installed in Oct 2007
6. Delayed engagement into first and reverse - can take 15 seconds or more to engage
7. No codes (no visible DTCs)
8. Fluid level full, pink color, Mobil 1
9.
10. Have not changed fluid or filter since install (3 months ago)
11.
12. No ATF fluid leaks under the truck when parked.
13. No electrical malfunctions
14. Engine is running a little rough at idle but is generally running strong. Prior to tranny install, code was thrown for misfire. This has not recurred since install.
15. Mods: see signature line - have Bama Chips tuner with an extra 10% bump on line pressure, otherwise running 92 performance tune at its out-of-the-box settings. Transmission is completely stock rebuild.
16. Transmission delays engagement of 1 or R for a long time on cold start. Engine freewheels when accelerator is pressed. This delay on one occasion lasted long enough for me to coast down my driveway, use my momentum to park, and think I was going to have to call a tow truck. when delay is this long, it usually helps if I turn it off and then restart.

Any ideas? thanks very much!

Edit: This only seems to happen when cold and does not recur on restart when warm. If solenoid malfunction, wouldn't it also fail when warm?

No, it's not a code. One of the main tranny guru's on the site has a list of everything you should provide for info if you want help. Info for 9 and 11 were already provided on other lines - see "Common Sense" sticky in tranny section.

From what you are describing, I would suggest replacing the O rings on the low/reverse servo with the viton D ring kit. If that does not help, then you could do a few other things, such as replace the EPC solenoid, add end plugs with O rings, add a boost valve with O rings, and a shift kit which mentions the delay with low, and reverse. Try the viton kit first before making a big job out of this. Find out if the transmission shop replaced anything on the valve body. You might be better off going back to the shop instead of investing time, and money. Any work you do might void the warranty.
