Truck slipping

Hi, I have an 03 Tundra 4.7L that has been an amazing truck since we bought it ne. We have kept upp all the maintenance (oil changes and Transmission changes) but recently have had a issue that keeps popping up The truck does fine 95 percent of the time but sometimes when we are going about 35mph and with the foot on the gas the truck seems to slip for a second and jolt ahead. This mostly happens when I am starting to go up a hill and instanly goes away if I mash the gas. My highly uneducated guess is the transmission or maybe the drive shaft.. What do you think?

Sounds more like the engine sputtering. How many miles on it?

It has 280k miles. The reason I don't believe it is the engine is that it always seems to be at a certain speed. I think an enigine would sputter at any speed. I may be wrong This never happens at low speeds or at high speeds or on the highway.

What does the tachometer do when this happens?

My guess is the clutch (manual transmission) or clutches (auto transmission) are slipping due to wear. A quick check is to repeat at a lower gear selection. If no problem, fix is to have the clutch(s) replaced. If problem, fix could be to have the clutch(s) replaced or maybe something else.

At that mileage it surely sounds like a transmission problem.

I agree that it's a transmission or clutch issue, based on the basic info given here.
My question is/was, is it an automatic or manual transmission.

Could be a ton of things at this point.
280K miles, could be many things ......

probably would go ahead and have it checked with a scanner to check for codes and scan the misfire counters also to see if its detecting a misfire on a cylinder if the problem does not occur often it may not set a light off.

Sorry for the slow reply. It is an automatic . I will tell my ife to look at the tachometer when it does it..I have not had to pay for a transmission rebuld for 30+ years. If anyone knows the ballpark cost of that, I am interested in your knowledge. I am trying to limp this truck for at least another year and hopefully 2 years.Toyota and Subaru are supposed to come out with small trucks next year and I don't mind spending a few thousand now to get me to when those come out. My wife does all the driving since I am going blind and she would like a smaller truck.

BTW.. Thanks for all the replies!

My wife had a Yukon transmission rebuilt about 7 or 8 years ago.. I think it was about $1800. I think that was done by an individual who has his own shop. So there wasn't all the overhead of a regular transmission shop or a national chain.

Today... maybe $3500 +/- $1000 ???

Thanks.. I will be looking for a local shop.. 3500 would be the tops I would be willing to drop on a 21y/o truck. Any more than that and I might lease a car for a year..
