Your Trans is definately slipping even though it doesn't seem like it. If this just started, DO NOT, I REPEAT DO NOT!!!! drive the car in this state, even with the SES light off it's still happening. You WILL have to get a rebiuld if you continue to drive it like this. Here's the deal of EXACTLY whats happening.... and no, an auxillary cooler won't remedy this problem.

(BEFORE SES LIGHT)

#1 - Valvebody gets stuck closed, insufficient tranny fluid to cool transmission.
#2 - Trannsmission gets HOT due to insufficient fluid, and begins to slip (explains lack of accelleration power)
#3 - Computer detects slip after about an half hour of highway speeds and engages the FAILSAFE which applies MAXIMUM LINE PREASURE to push the fluid to the transmission although this does not work due to stuck valve.... MAX LINE PREASURE is actually what causes your harsh 1st-2nd gear shift... before this it SEEMS to run perfectly fine although it's not...
#4 - The First it detects it in a running cycle, the computer just activates the FAILSAFE with harsh shifting WITHOUT the SES light... however the SECOND time it detects it in the next running cycle...then...

(SES)

#5...You get an SES light with the code P1870 (Transmission Component Slipping or 4X4 Transfer box)... PLUS FAILSAFE mode which activates harsh 1st-2nd gear shifting...
#6 ...You turn car off, turn car back on and everythings running fine??? Nope, problems still there, you just resetted your computer which deactivates FAILSAFE mode until it detects another slip....

You will COOK your transmission if you continue to drive it like this... Trust me I have a 97 V6 with an A4 (Same tranny) and had to get it rebiult because it got so hot in there it fried all the shift solenoids, Ironically I just got it out today. The Sonnax Kit listed above is the common remedy to this issue... After the kit's installed the problem will never happen again...

DIYer? I recommend a repair manual from your auto parts store. It should provide a complete list of all error codes and likely repair methods. Otherwise find a competent repair shop, or your dealer. I googled your error code This is just one of the answers: http://repairpal.com/check-engine-light-with-code-p1870-057
I am sure you can do a better search since you know far more about the issues.

I have a 1999 blazer I pulled the code p1870 if I change the control solenoid could that fix the problem?


Here is the definition of the code.
I doubt replacing an electrical component would do it.

P1870 CHEVROLET Description Transmission is in 4th gear with Torque Converter Clutch (TCC) engaged and the Engine Control Moduel (ECM) has detected excessive slippage when comparing the input shaft speed to the output shaft speed

I have 2 codes from AutoZone P1870 and P0113. What do they mean and can I fix them myself? If so what do I need to do?


P1870 is a transmission fault code having to do with the valve body, probably not a DYI job.
P0113 is a IAT (Intake Air Temperature) sensor circuit problem, could be a bad sensor or just a poor connection.

P1870 code what does it mean


This GM service bulliten might apply to your vehicle:

TSB # 01-07-30-023A
Harsh 1-2 Upshift, SES, MIL, or CEL Illuminated, DTC P1870 Set (Replace Valve Body)
1996 Buick Roadmaster
1996 Cadillac Fleetwood
1996-2000 S10 Blazer
1999-2000 Cadillac Escalade
1996-2000 Chevrolet Camaro, Corvette
1996-2000 Pontiac Firebird
1996-2000 Chevrolet and GMC Light Duty Truck Models
1996-2000 Oldsmobile Bravada
with 4L60-E Automatic Transmission (RPO M30)
Built Prior to January 15, 1999 (Julian Date 9015)
This bulletin is being revised to update the Parts Information

Please discard Corporate Bulletin Number 01-07-30-023 (Section 07 -- Transmission/Transaxle).
Condition
Some customers may comment on a harsh 1-2 upshift and the Check Engine Light or Service Engine Soon indicator is illuminated.
Diagnosis
Typically, these vehicles will have been driven more than 32,000 km (20,000 mi) before this condition occurs.
The scan tool may show a DTC P1870 set as a history code.
A harsh 1-2 shift or DTC P1870, caused by wear in the control valve body, may be difficult to duplicate when the transmission temperature is below 93°C (200°F).
Cause
The condition may be due to wear in the control valve body. This wear occurs in the bore that contains the TCC isolator and regulator valves, and results in poor, or no, TCC apply

Important
DTC P1870 is a type B code. The conditions for setting the P1870 DTC must occur on TWO CONSECUTIVE TRIPS (ignition cycles, with a drive cycle) before setting a P1870 history code.
When the conditions for setting DTC P1870 are met (first trip), the PCM commands maximum line pressure and harsh 1-2 shifts are the result.
This may result in a harsh 1-2 shift with no history code if the conditions for setting the DTC required for the second trip are not met, on two consecutive trips (Ignition cycles, with a drive cycle).

When the conditions for setting the DTC are met, on the second consecutive trip, a DTC P1870 is stored as a history code.
When the P1870 code is stored, the PCM will turn on the Service Engine Soon (SES), Check Engine Light (CEL), or Malfunction Indicator Lamp (MIL).
Correction
Install a control valve body with the revised TCC regulator and isolator valves. These valves are used in all transmissions produced after January 15, 1999 (Julian Date 9015), and all of the service parts currently available through GMSPO contain revised TCC regulator and isolator valves.

Important
If all of the following conditions are true, it is not necessary to rebuild the transmission or to replace additional transmission components beyond the control valve body.

Transmission operation is normal before the transmission reaches operating temperature, or before DTC P1870 is set (no slips, flares, or missing gears).
The torque converter is not blue or overheated.
The transmission fluid is not burned or has no burned odor.
The transmission fluid pan contains no abnormal debris (clutch material, bronze, brass, or metal fragments

Not shifting right


Here's was the code means:
P1870 Transmission Component Slipping

A code that indicates a problem with your tranmission. Ususally causes a hard shift from 1st to second gear. Need to have a transmission expert look at the vehicle. Most cases the torque converter is the main problem. But, sometimes the transmission may need rebuilt if damage has occurred.

Emmission codes, Mass air flow sensor


The P0101 code is indeed a code indicating an issue with the MAF sensor. It could be something as simple as cleaning the sensor, or it could be faulty and in need of replacement.

Now, the P1870 code refers to the transmission, and a condition in which the PCM is detecting excessive slipping. That is to say it perceives the transmission slipping as it compares engine speed (RPM) and vehicle speed (MPH) and should a ratio be exceeded then the PCM will set code P1870. I would expect that you would notice a bit harsher shifting in response to this code, particularly on the 1-2 shift as the PCM will command higher fluid pressure to combat the slipping.

Now, it is possible that the an issue with the MAF would cause signals to the PCM to change significantly and to such an extent that the PCM would think something is off with the transmission, so I would start there, with the MAF sensor and see if that helps as it appears you were already thinking.
