Hello Everyone!

I am brand new to these forums. My name is Justin, I am 30, currently married and raising our son who is 4. I live in Michigan, southeast Detroit (canton) We just currently bought a 1999 Oldsmobile Bravada from a used car lot. It has 143k miles. I have a list of OBDII Service engine light codes. Most of the codes I can not find on the internet.

Can anyone help look these codes up for me? I have googled them, BING, and a few other search engines. Can't find anything.

:CODES:
P0135,
P0463,
P1133,
P1870.

I found the first code I got myself which was P0135 (Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)

Any help would be greatly appreciated!!

P0463 Fuel Level Sensor Circuit High Input
P1133 o2 sensor Bank 1 Sensor 1
P1870 is a transmission slipping code if i remember correctly. might need a rebuild. id take it to a tranny shop that will scan it for free to make sure, but i think im right on this one.

Before you rebuild the tranny, change the fluid to Dextron VI. You will also want to update your transfer case fluid and front transaxle fluid.

We have each codes herel

At this point I am sure that the tranny is slipping. I have only taken it out on about 5 trips. When I start it and first accelerate in drive it doesn't seem to want to go. It hesitates and then jerks. This only happens when I first start it and try to get it going. Once on the road it doesn't do so much of the slipping, but I can tell it'* not as smooth as it should be.

A transmission rebuild would cost me quite a bit of money, especially since I cannot do the work myself.

Thank you all for the help. I really appreciate it.
