TRANNY ACTING WEIRD

[skter97]

Well last nite i was driving and i was going about 55 mph and when i tryed to give it gas it just reved up like it was in neutral it did this several times when i tryed to give it gas, i pulled over and put it in park then started driving it again and it shifted fine for a while, then i went to 7-11 and when i was backing out of my parking spot i went to put it in drive and it would just rev up and not go into drive at all, finally after about the 3rd try to give it gas it finally popped into gear, i drove it around for about an hour after that and the tranny acted fine... i went down to the 210 tune now just to play it safe for awhile, i think my tranny or the converter dosent have much life left so thats why im running the 210 tune and im gonna take it easy on the tranny, gonna take it to my ford dealer this sat and have them check it out to see if they find anything at all!!!

sounds like the shift solenoids have "debris" in them. That "debris" is undoubtedly some part of your clutches. You can replace the solenoids, and it will probably work for a while longer, but most likely you will be throwing money away. They will fail again, and more importantly you probably don't have much clutch life left.

Most likely what you need is a new TC, a superduty kit from Suncoast, and new solenoids. The superduty kit has the cooler line filter in it. This is probably the most pertinent part for you.

I've never tuned a diesel before and I'm REALLY worried about burning up my engine/tranny so I've been following all the problem threads recently to learn as much as i can and I'm just curious as to the history of your truck.

What tune do you have on it? What level do you run it at? How many miles did it have when you installed your tune? How many miles have you been running with the tune? How do you drive it? Are you racing it? Towing? Pulling?

I plan on going pretty easy on it, maybe tow the boat twice a year, and from what I'v gathered I shouldn't have any problems as long as I'm vigilant with servicing/monitoring it. Spartan makes it sound like you're not putting your truck at risk if you're not an idiot or don't go crazy with it. Just trying to back that theory up. Thanks for any info you can provide!
