Mitsubishi challenger 2.8 turbo diesel 1999 automatic, when standing still on tick over at a junction in gear their is no acceleration when trying to move off for about 5 seconds then it picks up speed and moves off and is then fine until the next time you stop at a junction again.

Is the transmission slipping? Has the transmission been serviced every 50,000 km?

If you feel it is an engine-related problem, the link below may help:

With all diesels, it's important to purge water and change fuel filters regularly. Likewise, it's important to provide plenty of clean air, especially on turbo diesels. If you don't you can bend the turbine blades. Therefore, you want to change the air filter at least as often as recommended in the Owner's Manual. Since you have a turbo, you only want to use the appropriate full-synthetic diesel engine oil. Ensure the oil is filled to the "Full" line. On some diesels this can affect fuel pressure. I would never use conventional oil in a turbo diesel--they can't take the heat. Turbos can spin at 50,000 rpm for several minutes, even after the engine is turned off.

I suspect there may be a turbo-related problem (check for coking). Diesels are more durable than gasoline engines, but require a higher level of maintenance. Start a Maintenance Log (Date, Mileage, Maintenance Performed) and do things by the "book." For any engine or transmission problem, I would have Mitsubishi do the work. Good diesel mechanics are few and far between.

Tanks for that since I have had the truck it had a good service record but not on the automatic box I will drop the fliuid and replace it with new and see how it goes, I will have a service at the same time thanks for your hel

It would be best to also use a full-synthetic automatic transmission fluid, such as Mobil 1 Synthetic ATF. It meets Mitsubishi's Diamond SP-II and SP-III requirements.

When you have the service performed, drop and clean the pan, change the filter, refill with synthetic ATF, and record it in your Maintenance Log. Maintenance Logs on my vehicles are kept in Microsoft Word, using the "Table" format.

The truck has hd to be towed into a garage today, it will accelarate in nutral and park but would not accelerate in drive so the car would not drive
