Transmission Slipping on Takeoff

edwardsgs · #1 09-11-2007, 04:35 PM

I have a 1993 F150 XL 4x4 with a 4.9 liter 6 cylinder engine with an automatic transmission. The transmission frequently slips just a bit whenever I take off. I try to do a slower take-off to hopefully keep from damaging it but it still slips. If I continue to drive it like this will it gradually get worse or break all together? Will I further damage the transmission by continuing to drive it? In other words will this cause me to require a new transmission versus getting mine rebuilt?

1. Have you checked the fluid level? (Sorry if I insult you with this question, but the only stupid question is the one that remains unasked)

2. How many miles on the truck, and how often has the fluid been changed?

Thanks for the reply. The transmission fluid is a little high if anything. I had the transmission fluid changed to see if it would help, but it didn't. The truck has about 117,000 miles on it. It has been worked hard. It was a Department of Transportation truck first, then a farmer owned it before I bought it from him.

Sorry to say but you better start saving up for a rebuild!
When they start slipping like that it's just a matter of time.

That What My Transmission Did Right Before It Blew Up. I Would Go To The Auto Parts Store And Buy Some Lucas Automatic Transmission Stablizer. I Heard It Works Great.

Lucas wouldn't hurt, but you will need to suck some fluid out so it won't be overfilled. It may help you get a little more life out of it, but you definitely have a rebuild in your near future.

Well, I have a fishing trip to Cape Hatteras scheduled for November. I guess I need to have it done before then. Thanks for your replies.

When you get your Tanny rebuilt make sure they replace everything. The sensors, all the clutches and the nuetral saftey switch. Good luck. I paid 1,200 for mine to get rebuilt and I aslo got a shift kit installed and it makes a big difference. Good Luck

My stepson's '93 Ranger is doing the same thing. I took it to the dealer, and they quoted me $2000 for a rebuild, or $2600 for a factory refurb with a 3 year, 75,000 warranty. If the truck were worth more, I would have gone with the factory refurb, but instead, I found a used tranny for $200 and install for $250 cash. If he gets 50-60K out of it, I will consider it money well spent. I'm not about to put $2000+ in a 14 year old truck......
