make sure connections on adjustment rods for tranny r tite n not "slippin"...always chek for bent linkage if u can't get it just the way u want it...especially if u have been speed-shiftin...

As bowtie352 said, according to the Hollander number only 98 & 99 will fit your truck but just in case you didn't know the Ram 2500 and 3500 should fit as well in 99 & 98. the ID # for the 1998 is 52119516 & in 1999 the ID # is 52119823. By the way the Hollander # is 400-3256. I have been in the auto repair business for way to many years but have come across a problem with this very transmission a number of times. I I can't remember the daignostic trouble code (DTC) but this problem did cause the check engine light to come on and did receive a DTC dealing with the transmission. The symptoms that the customers transmission was having was that the transmission would not downshift back to first gear and the vehicle would start from a stop in higher gear and not in first gear. Now the reason I am mentioning all the is that I have tried changing the wire harness inside the transmission and this solved the problems in all of them except a couple of them. Not saying this will fix your transmission if you are dealing with the same problem/symptom just letting you know of my experience with this same transmission. The Dodge dealership does sell this wire harness as a separate part and I think the retail cost of the harness is somewhere around a hundred daollars. Hope this helps...

Are you saying you put in a new but used tranny and it still dosent go out of first gear? Or are you saying you replaced a tranny line? If its the tranny you replace and first is the only gear you may not have adjusted the shifting linkage correctly. Put the truck in park and loosen the linkage on the tranny and slidr the rod on the tranny back and retigten and try that

your transmission runs through part of the radiator. Check your fluid level and see if your hoses are conneced right.

You need to get your tranny rebuilt. The motor that is already in your truck is set up for that Tranny so i wouldnt change it at all as it would cost alot more then you need to spend to do it. . I also would go to Mr.Transmission as they do great work on trannys.

I'm not possitive but there is usually a vent tube on top of the transmission, may be possible that dirt or something is clogging it up. That would cause the tranny to build up pressure. But to blow the seal on a new radiator, I wouldn't imagine that. My opinion would be that the new radiator wasn't put together correctly. But just in case the vent tube did cause it to let go, check the vent. I hope that you find the problem. Best wishes.

the gears in transmission are going out..aka slipping.....check out pavementpounders.com or gotmud.com they cn help you out better on there than on here

Sorry this is not an easy fix the clutch packs in the transmission are slipping, usually caused by wear, but the hydraulic pump is probably getting week. As the oil warms up the oil gets thinner and the hydraulic pressure decreases. Times for a overhaul of the transmission, and if the torque converter can not be flushed a new torque converter is recommended. You may get lucky buy changing the fluid several times, but if the transmission is 22 years old it may not help.
