Default No o/d and Roar when start to move.

Hey Guys just wondering if anyone has ever had this problem.

Ive been reading for about a day now and cant find anything.

First off I own a 95 Ram 1500 318 auto. The tranny is tired but still shifting to 3rd but no o/d.

Also Once i start moving up to all speeds theres this roar coming from i think the tranny because i put it up on jacks and i dont hear it coming from brakes or rear end.

Any input would be appreciated need transportation going to be drving on highway for a bit.

Throwing codes:
17 Engine stays cool too long (bad thermostat or coolant sensor?)
15 No speed/distance sensor signal
37 Trans temperature sensor voltage low

Welcome to DF!!!

Does speedometer work?

OD and TCC operation will not occur unless it has a speed reading

if it does go into OD/4th but TCC will not lock then truck is not up to operating temp. - bad sensor or wiring

what does your Coolant temp in cluster say?

That overdrive is the real weakpoint on our trannies, so you might want to check out that tailhousing chrysler "engineered" on. Also, that roaring sound could possibly be your pinion bearing in the rear differential, or the front one, if you keep it in 4wd.

No Speed and Coolant temp stays around 190-210.
Also its a 2wd is the diff the only noise it can be.
