Thread: Possible Transmission Problem?

Think I would be okay if I got a Bosch one, or would you advise against that brand. Also I talked to my mechanic who said its perfectly fine to go from my stock 110A alternator to the 200A so I'm fine with switching now (I think I'll add a sub and some aftermarket light and maybe a train horn since I'll have a bunch of extra power potential lol). ---------- Why I'm on the subject of transmissions, Alfie would swapping my transmission cooler for a larger one be too difficult? My truck came without the factory tow package and during the summer my trans temp sometimes gets to 170* in traffic and on the freeway (also I have plans for things I'll need to tow, already have a hitch installed). I remember DJ on here saying with his he usually sits around 130*, just curious because I know trans fluid starts breaking down somewhere around 200* and I'd like to extend the life of both my fluid and my transmission by keeping it cooler. Also what else does the factory tow package entail besides a tow hitch, 7-pin connector, and larger trans oil cooler, anything else? I think there's another engine oil cooler too right or no?

i heard that turning off the overdrive will keep it cooler when it's stop and go traffic but I'm not sure..

That won't do anything, all the overdrive button does is disable the transmission from shifting into the highest and most efficient gear. Its designed for saving your brakes by using your engine as a brake when going down steep slopes. It limits the speed you can go because it's limited to a lower gear, you hit higher rpms but essentially go slower because you can't go faster without shifting. Turning it off when you're nowhere near shifting into overdrive will do nothing, as far as I know, to aid in cooling the transmission.

transmission range sensor! !! I spent 2 weeks replacing every switch and relay finally found it

.. Thanks for then help lmao I didn't know that it slowed it down

It's all good we're all hear to learn. And yeah it basically just uses your engine as a brake to save your actual brakes on steep downhills.

While it may be fine to upgrade from a 110 to 200, I would look into weather the wire going from the alternator to the battery can handle the extra amperage with out melting. You could always run a seperate wire with a fuse or circuit breaker if you find the stock one isn't up to the task.

my brother says only new cars do that? I'm confused

Nope, they've had it for awhile. In the old school days instead of O/D they had the gears like what we can shift into like 1 and 2, but many of them had 3 that you could manually shift your automatic transmission into, basically a manual overdrive.

Good point, my mechanic just said it would be fine because its not increasing the voltage not the amperage, but that was for when I asked about the voltage regulator. I'll have to check into the battery cable. Thanks Ted!
